The Alamo Plaza Historic District is an historic district of downtown San Antonio in the U.S. state of Texas. It was listed on the National Register of Historic Places in 1977. It includes the Alamo, which is a separately listed Registered Historic Place and a U.S. National Historic Landmark.

In the early eighteenth century, when, upon arrival of Spanish Catholics, local Native Americans asked the Franciscan missionaries for permanent shelter and protection from rival tribes, they were provided shelter within the missions in exchange for conversion to Christianity. They were also given Spanish names.

Alamo Plaza's layout and landscaping were designed and supervised by city alderman Anton Wulff during the late 19th century. In recognition of his work on behalf of the area, local business leaders presented him with a gold-topped walking stick, engraved with words of appreciation.

The district originally included 27 buildings or structures:

1. Menger Hotel, 204 Alamo Plaza. "Built in 1857 the Menger was originally a two-story limestone building designed by John Fries. Located at the southwest corner of the block the building later expanded to a three-story building at this corner. Alfred Giles is responsible for this later design. The west façade of the original building is now a three-story, three -bay structure. The slightly projecting central bay is crowned by a pedimented parapet. The first floor contains a central door flanked by two windows, while the second and third floors each contain three round arched openings. The end bays contain two flat arched windows on each floor and these pavilions are capped by a bracketed cornice. Iron balconies extend at the second and third floor levels. Additions to the north and east have been made several times in the 19th and 20th centuries and the hotel now fills the entire block. A lavish three-story space in the Menger lobby, illuminated by a stained glass, leaded skylight, dominates the old part of the hotel. The solid block of hotel buildings is broken in the center by an interior courtyard of walkways through dense tropical foliage."
2. Dullnig Building (1883), 101-103 North Alamo, a three-story Italianate-style brick building built for George Dullnig to serve as a grocery and dry goods store. A ten-foot false façade tops the building, where a cornice once was.

The second floor (on which side? check Google Streetview) "contains three segmental arched windows separated by brick pilasters. A brick corbelled cornice is crowned by an arched parapet of pressed tin containing the company's name. The two adjacent buildings at 119-121 North Alamo are compatible in scale but their façades have been altered."

The three-story buildings are joined visually by a pressed tin cornice, but the façades of the two center buildings have been covered by a false front. Although they have been altered on the first floor, the two outside buildings retain their original arched openings on the second and third floors.

Each unit contained a broad central light of plate glass, fixed, and narrow side lights with an opening sash. Each of these lights contained a transom. A frieze and slightly projecting cornice terminated the building. This early 20th century commercial building replaced an elaborate 1886 Victorian structure, designed by Alfred Giles. The bank was the first five-story building in the city and contained continuous balconies on all four levels.
17. Moore Building, Northeast corner of Houston and Broadway The Moore building is a six-story brick building stuccoed and scored to look like stone. Constructed in 1904, the building is basically rectangular with an angled southwest corner to mark the main entrance. Scoring accentuates the angled corner as well as the two flanking bays at the second, third and fourth levels. On both the south (Houston) and west (Crockett) façades fenestration is organized in vertical bands between three-story pilasters that are linked by arches at the top. A small cornice elaborated by terra-cotta swag and cartouche motifs marks the fifth floor, while a dentilled cornice emphasizes the 6th floor. Terra-cotta details further embellish the divisions between the paired windows on the 5th and 6th floors. Crowning the structure is a projecting pressed tin cornice. The building originally had a roof garden above the fifth floor with pavilions at four corners. An alley off Houston provided access to the elevator. In 1909, the addition of the sixth floor replaced the roof garden and expansion to the east closed the Houston Street entrance.

The third through the seventh floors contain little ornamentation, but the top floor is articulated by a string-course and elaborate sculptural detail between the windows. Terminating the building is a bracketed cornice with modillions and dentils. The remainder of the buildings along Houston between Alamo Plaza and Broadway, as well as the buildings along Broadway behind the 300 block of Alamo Plaza, are not significant architecturally or historically, but they are compatible in scale and use.
19. Post Office and Federal Building (San Antonio, Texas), 615 East Houston. The Post Office is a four-story limestone Renaissance Revival building located in the prominent position at the north end of the Alamo Plaza. The building was designed by Ralph Cameron and built in 1937 by the Works Progress Administration. The ground floor is rusticated and contains the entrances, but the dominant feature of the main (south) façade is the classical colonnade in antis on the second and third floor. A cornice divides this level from the final story. The Postal Service first moved to Alamo Plaza in 1877 on the northwest corner of the present Joske's block. In 1886, J. Riely Gordon supervised construction of a Romanesque Revival building at this location. The present building replaced the 1886 Post Office.

The first two floors are faced with stone and contain widearched window spaces. The upper portion of the building is brick with terra cotta detailing. The Medical Arts Building represents a commercial example of the Chateauesque style with its corner tower and steeply pitched mansard front at the top floor, surmounted by cresting and containing the wall dormers with high pinnacled gables. Elements of both the Gothic and Renaissance styles are evident in the detailing. Gothic features pre-dominate in the pointed arched openings of the first two floors and in the upper two floors of the tower.

Within the wide central bay a slightly projecting main entrance is off center and is defined by a rusticated stone arch. The remainder of the first floor openings have stilted arches with a keystone and rusticated voussoirs. On the second floor above the main entrance are polished granite pilasters that frame a window with a pedimented entablature and square transom. An identical window is contained in the southeast projecting pavilion. The remaining windows have round arched windows supported by small granite columns, and are surmounted with a corbel table.
