Mosta (Maltese: Il-Mosta) is a small but densely populated city in the Northern Region of Malta. The most prominent building in Mosta is the Rotunda, a large basilica built by its parishioners' volunteer labour. It features the world's 3rd largest unsupported dome, and displays a replica of a German bombshell that famously crashed through the dome but did not detonate upon impact.

Mosta celebrates the parish feast of the Assumption every 15 August. Mosta's feast day celebration is popular amongst both locals and tourists. The city is annually decorated by local parishioners and townspeople, seeking to demonstrate their affection for the city and its patron saint, weeks ahead of the public procession.

Mosta has been inhabited since pre-history. Dolmens in the limits of Mosta and cart ruts are primary evidence of this. Each dolmen has two rectangular standing stones and one other similar stone positioned horizontally above the other two.

In the Middle Ages, Mosta was a small hamlet amongst a number of other hamlets, each sparsely populated. These tiny villages were Raħal Calleja, Raħal Ħobla, Raħal Pessa or Pise, Raħal Sir, Raħal Kircipulli, Raħal Brabar and Raħal Dimech. In the 16th century, these hamlets decreased in importance and Mosta took its place as the principal village. The Apostolic Visit of Mgr Pietro Dusina in 1575 indicated that even the church dedicated to the Assumption that stood in Mosta was so important in the area that it was erroneously called ‘parochial church’. In 1575, there were 580 persons living in Mosta.

Mosta is, in contemporary times, witnessing the construction of many new houses. New built-up zones with residential houses are found on the outskirts of older Mosta. These new zones are known as: Santa Margerita, Tal-Blata l-Għolja, Iż-Żokrija, Is-Sgħajtar and Ta’ Mlit. This means that the population of Mosta is increasing. Mosta has also become a bustling commercial centre. All these developments have made Mosta a big town by local standards and it is today amongst the largest in the Maltese Islands.

As Mosta is at the centre of Malta; buses pass through Mosta on the way to Buġibba, Burmarrad, St. Paul's Bay, Qawra, Xemxija, Mġarr, Ċirkewwa and Mellieħa.

The town has several legends such as The Bride of Mosta (L-Għarusa tal-Mosta).

Mosta has its own scouts and girl guides, two band clubs (Nicolo' Isouard and Santa Marija), and two fireworks factories (Santa Marija and 15 ta' Awwissu). A lot of traffic passes through Constitution Street, one of Mosta's main streets, connecting the south to the north.

Mosta boasts the third largest unsupported dome in the world. The church, also commonly known as the Rotunda of Mosta or the Mosta Dome, is dedicated to the Assumption. The Feast of the Assumption is held on 15 August and it is a public holiday in Malta.

From its inception as a parish in 1608, Mosta has had three different churches built on the same site, with the current one being designed by Giorgio Grognet de Vassé, a French resident of Mosta. The Mostin at that time, totalling not more than 1500, built the church.

Grognet’s design was based on that of the Pantheon of Rome. Due to debates and doubts regarding the design, the first stone was laid on 30 May 1833. The rotunda has a diameter of 55.20 metres on the outside and 39.60 metres on the inside. The main façade faces south and has six columns in the Ionic style. On each side, a steeple rises from the façade. Following the front elevation, the church has an analogous style at the back, but without steeples. The dome was built on the principle of the catenary profile, meaning that each stone was laid over the one underneath it.

The church took 27 years to complete and became a major attraction. On 9 April 1942, the church was nearly destroyed during World War II. An Axis bomb hit the dome of the church whilst people were inside, but it failed to explode. The detonator was removed and a replica bomb is now displayed as a memorial.

A prominent feature of Rotunda Square is a statue of a lion on a pedestal, which was removed in 2023 and placed in the public garden behind the church. Once, this was part of a fountain which originally was in Sliema. The fountain has since been removed. The statue is made of bronze-coloured cast iron. It was made in the Val d’Osne Foundry in Paris. Embossed on the pedestal there are the coat-of-arms of Mosta and those of independent Malta.

The Ta' Bistra Catacombs are the largest set of catacombs found to date outside Rabat, and are located in Triq il-Missjunarji Maltin in Mosta. These catacombs were first recorded in the 1800s but were only investigated in 1933 by Captain Charles Zammit, before part of the site was covered over by a new road leading down to Burmarrad. Further studies in 2004, 2013, and 2014, have brought the site back to life with new discoveries. This site has been part of three EU-funded projects and is now managed by Heritage Malta.

An attraction in Mosta is the Speranza Chapel in the Speranza Valley. The chapel was built between 1760 and 1761. A legend tied to the Chapel recounts that, during a Turkish invasion, a young girl and her sisters taking care of their family's sheep were at risk to be taken by the invaders. Whilst the sisters escaped, the young girl could not run fast enough because she limped slightly. It is said that she hid in a cave found under the chapel's left side. Meanwhile, she prayed to Mary, promising that if she were saved, she would build a chapel dedicated to Our Lady. When the Turkish invaders chasing her arrived, they didn't look for her in the cave because they thought the girl could not be hiding there as there was an intact web at the entrance, which would have been damaged had she entered the cave.

The Marquis Mallia Tabone Farmhouse is a folklore attraction run by the Talent Mosti philanthropy in collaboration with the adjacent school's council. The farmhouse overlooks the valley of Wied il-Għasel. It houses exhibitions varying from paintings, photography, artisan work, hobbies and a permanent folklore museum.

Two dolmens, dating back to the Bronze Age, can be seen in a field between Vjal Ragusa and Dawret il-Wied.

The Cumbo Tower is a fortified residence in Mosta. In the grounds there is a small Christian family tomb from the Roman era.

This is a site that has most likely been destroyed, and has been recorded by Emmanuel Magri as being in the hamlet of Ħal Dimech, now part of Mosta, and not far from the Ta' Bistra Catacombs.

Within the grounds of Fort Mosta, there is a small catacomb. Originally, this was a Punic shaft tomb but it was enlarged into a Roman period catacomb complete with an agape table. This site is within the confines of Fort Mosta which is used by the Armed Forces of Malta.

Another small catacomb is found in Wied il-Għasel, consisting of a series of seven tombs dug in the rock in a semi-circular form found in the side of a natural cave beneath Fort Mosta.

In a 2008 publication, then Mosta Mayor Dr Paul Chetcuti Caruana stated: "As many know, and no one knows, in the neighbourhood of Ta’ Bistra there is at least one Roman temple which has been buried by the speculators."
