Mosonmagyaróvár (Hungarian: [ˈmoʃonmɒɟɒroːvaːr]; German: Wieselburg-Ungarisch Altenburg; also known by other alternative names) is a town in Győr-Moson-Sopron County in northwestern Hungary.

The city is also known by alternative names in other languages: German: Wieselburg-Ungarisch Altenburg, Latin: Ad Flexum, and Slovak: Starý hrad.

The area around Mosonmagyaróvár has been inhabited since the 5th millennium BC, but settlement of the city proper can only be traced to around the 1st century, which was when the Roman Empire was extended to the Danube, creating the province of Pannonia.

The purpose of Ad Flexum was to defend the Mosoni-Duna, but the security the legions provided also drew civilian settlement, especially since a major east–west trade route ran through the area.

Circa 170 AD, Germanic barbarians who lived north of the Danube river attacked the settlement, nearly completely destroying it.

Settlers flocked around the wooden and then stone castle, and by the 11th century it was described as a strong fortress and bustling merchant town; by this time, it was also the county seat of Moson.

Béla IV, King of Hungary at the time, did not consider it worthwhile to try and rebuild the castle at Moson, and thus turned to Óvár as a promising site for a future fortress.

The King gave a man named Conrad, who was of the Győr tribe, lands in Moson and funds to be able to accomplish this task.

After Louis II's marriage to Mary of Habsburg, Óvár became a key defense on the Austrian border, which would come into play during the Turkish invasion.

In 1529, after the Turks were repulsed at the Siege of Vienna, they destroyed Óvár almost completely, leveling all of its Medieval buildings, including the castle and the Romanesque church.

Due to the lax nature of the new statutes, and the rights of the townspeople as enforced by Ferdinand and Archduke Maximilian, however, religion did not become compulsory.

The Austrian government wished to limit the independence of the town, but the people were able to hold on to a degree of autonomy; an agreement to this effect was signed in 1796 after delegates had been sent to Vienna and Buda.

After the reestablishment of the current Representative Parliamentary Democracy in 1989, the Young Democrats controlled the city administration for a few years, expanding tourism and making developments to the gas and sewage infrastructure.

Compared to economically wealthy countries where dental care is expensive, low business overheads in Hungary allow clinics to offer their services at extremely competitive rates.

In addition to dentists, clinics and guided tour providers, the local hospitality industry as a whole lives off the dental tourist trade.

With nearby international airports in Bratislava, Budapest and Vienna, Mosonmagyaróvár even attracts patients worldwide, travelling from as faraway as Greenland, Canada and the United States.
