St. Raphael's Cathedral is a Catholic cathedral and a parish church in the Archdiocese of Dubuque located in Dubuque, Iowa. The parish is the oldest congregation of any Christian denomination in the state of Iowa. The cathedral church, rectory, former convent, and former parochial school building are contributing properties in the Cathedral Historic District on the National Register of Historic Places.

St. Raphael's Parish traces its origin to July 1833 when the first group of settlers gathered for Mass in the home of Patrick Quigley. Father Charles Felix Van Quickenborne, a Belgian Jesuit, organized them into a parish. The parish did not have a regular church building yet, so the members met at various homes for mass. Father Quickenborne began planning for a church building, but left before the materials were assembled.

Father Charles Francis Fitzmaurice arrived in the area in 1834 and began working with the parish. He gathered materials and money to build the church, but he died during a cholera outbreak in the spring of 1835. He did not have a chance to begin work on the church building. For a time, the parishioners met in a log cabin that was set aside for worship.

The next pastor, Father Samuel Charles Mazzuchelli, OP came to Dubuque later in 1835. He reorganized the parish and dedicated it to the Archangel Raphael. Under his guidance, a stone church building was constructed. Father Mazzuchelli personally drew the plans for this building, which served for the next 25 years. It was located just south of the current cathedral.

In 1837 Pope Gregory XVI created the Diocese of Dubuque. In 1839 Bishop Mathias Loras, the first Bishop of Dubuque, arrived after first going to France to recruit priests and raise funds to operate the new diocese. St. Raphael's became the cathedral church for the diocese.

The next 20 years were a period of growth and expansion for the parish, and of the Church in general in Iowa. Bishop Loras encouraged both Irish and German immigrants to come to Iowa from the crowded conditions in the eastern United States. As a result, the parish began to grow in size.

By 1845 St. Raphael's was usually quite crowded on Sundays. In 1849 there was a number of German families in the parish. Because of the crowded conditions, and because of the challenges of ministering to them, Bishop Loras granted permission for the Germans to form Holy Trinity parish in Dubuque. The parish eventually became known as St. Mary's. In 1853 St. Patrick's Church was built 12 blocks north to serve as a second parish for Irish families. Loras, however, made it a mission of St. Raphael's so he would not lose the income he needed to build a new cathedral. This created problems between him and the local Irish community.

After St. Patrick's was founded, Bishop Loras soon came to realize that the founding of those additional parishes would only be a temporary solution. He realized that St. Raphael's parish needed a larger building.

The new cathedral was originally planned to be built on a "Bishop's Block" on Main Street. As the city's business district began to encroach on that location, Bishop Loras terminated the plan. In 1857, construction began on land just north of the old cathedral building. On July 5, 1857, a large crowd watched as the cornerstone was laid. The cathedral was based on Magdalen College in Oxford, England. The architect was John Mullany, a local architect who designed New Melleray Abbey, and St. Mary's Church. He originally designed the cathedral in the Romanesque Revival style, however, the Panic of 1857 forced a change in plans and it was constructed in the Gothic Revival style instead. Despite his failing health, construction had advanced far enough that Bishop Loras was able to offer the first mass in the new cathedral on Christmas Day, 1857. He died two months later.

Construction on the cathedral, without its complete tower, was finished in 1861. The formal blessing and dedication were done by Bishop Clement Smyth, OCSO, on July 7 of that year. Father Mazzuchelli assisted with the dedication. St. Raphael's is a brick structure built on a raised basement and a stone foundation. The lower part of its 130-foot (40 m) central tower is limestone. The three naves on the interior are divided by fourteen clustered wooden columns. The side elevations are seven bays in length. They are divided by buttresses and each has a lancet window in the center. Smaller windows are located over the side altars and there are three windows on either side of the chancel. Above the main entrance is a large lancet window. It was part of the original plan for the building. Even though the design of the cathedral was changed several times, the window was left as originally designed in each plan. The upper part of the window is visible from inside the church, while the lower part is hidden behind the organ.

The cathedral's tower was finally finished in November 1876. The original plans called for a 243-foot (74 m) tall tower and spire, however after construction began to complete it, cracks started to form on the front wall. Instead of stone, the bell-chamber at the top of the tower is a wood structure that is encased in galvanized iron painted to resemble stone. Four tall pointed pinacles (no longer extant) were placed at the corners. New entrances were cut into the sides of the tower and the main facade of the church building was covered with Portland cement and made to look like stone.

Dubuque architect Fridolin Heer designed the chapel built in the back the cathedral in 1882. The new building obscured the three stained glass windows above the altar, so they were removed and placed above the altar of the new chapel. It served for nearly a century as the Blessed Sacrament Chapel, and its interior was briefly seen in the movie F.I.S.T. (1978). A number of other renovations were begun in 1886 according to the designs of Chicago architect J.J. Egan. They included new vaulting made of iron and lowering the column's capitals down by 4 feet (1.2 m). The interior was replastered, new Stations of the Cross were imported from Germany, a new gallery was installed in the rear of the church, and a large arch was cut into the tower to allow light from the lancet window to brighten what once was a dark nave. The frescos in the church were completed at this time by Luigi Gregori, artist in residence and professor at the University of Notre Dame who had previously worked at the Vatican, and his son Constantine. Bishop John Hennessy rededicated the cathedral on November 21, 1886. New stained glass windows, whose openings in the nave had been lowered 2 feet (0.61 m), were imported from London and installed in 1889.

In 1902, a mortuary chapel was built in the lower level of the cathedral. Contained within this chapel are vaults buried underneath the floor in front of the altar. These vaults contain the bodies of former Bishops and Archbishops of Dubuque. Four of Dubuque's Archbishops are buried elsewhere. Also buried in the chapel is Archbishop Raymond Ettledorf - a local priest who became Nuncio to New Zealand and parts of Africa. The altar and communion rail are made of Italian marble.

Two more renovations were done in the first part of the 20th century. The first was done in 1914, and the second in 1936. A new expanded main entrance was built in 1966. The addition contained new staircases that replaced the old outdoor stairs that originally led to the side entrances. Three new sets of doors were placed at street level. Also, an elevator was added to make the building more handicapped accessible. The chancel was also altered in the wake of liturgical reforms from the Second Vatican Council. Archbishop James Byrne celebrated the first Mass in English at St. Raphael's.

In 1986, the most extensive renovation in years was done to the church. At the time, it had been more than 50 years since the renovation. Also, the parish wanted to make some updates to the design which coincided with certain architectural and liturgical trends that were emerging in the Church at the time.

Work began in the late summer and fall of 1986. The Eucharistic Chapel was deconsecrated and remodeled into a gathering space for the parish and renamed the Cathedral Center. A new Eucharistic Chapel was created by placing a wooden screen between the original high altar, and the new ad populum-oriented altar. Portions of the original communion rail were used in construction. The original ad absidem altar was left intact because of its historical significance, and a new tabernacle was placed on the altar.

Because they were a fire hazard, the dividers between the pews were removed. The layers of varnish applied over the years to the woodwork were also removed, which was refinished to allow the light oak to show. The walls were painted a lighter color, and a new indirect lighting system was installed. A light green carpet was added and used throughout the building. Part of the Pietà altar was refurbished and installed in the sanctuary as the new main altar, replacing an early 1970s altar.

The sanctuary platform was extended so that more of the liturgical functions associated with the Mass took place closer to the congregation. The archbishop's throne was replaced with a smaller, movable, less elaborate cathedra that allows him to directly face the congregation during Mass.

By November 1986 the renovations were complete. The remains of St. Cessianus were installed in the main altar during the first Mass held in the renovated Cathedral on November 23, 1986, celebrated by Archbishop Daniel Kucera, OSB. This is in reference to the tradition in the early years of the Church when Mass was often celebrated over the tombs of saints and martyrs. The bones of St. Cessianus, a second-century Roman martyr, constitute the Patronal Relic of the State of Iowa. Pope Gregory XVI presented them to Bishop Loras in 1838.

A pool was added to the baptismal font in 2005 for immersion baptism of older children and adults. It was completed in time for the Easter Vigil that year.

St. Raphael and St. Patrick parishes were linked in 2010 by Archbishop Jerome Hanus, OSB. The two parishes share the same pastor and they work closely together on various programs.

The cathedral's pipe organ was originally built in 1890 by a builder now unknown, and was rebuilt by the Tellers-Kent Organ Company in 1937. It has 46 ranks, with three manuals. The organ is composed of a number of chambers in what was the choir loft, plus another chamber along the southern wall near the front of the church. There is also a set of chimes attached to the organ.

Like a number of other organs, the pipework is largely left out in the open rather than being contained with the case. The pipework was artistically arranged to make a stunning visual display.

The organ console is situated in the choir area on the main level near the front of the church. It can be moved for various functions, such as Mass and recitals. In 1991, the organ was refurbished after several years of fundraising. The organ is one of the larger ones in Dubuque, and is considered one of the finest in the city.
