Pressburg flourished during the 18th-century reign of Queen Maria Theresa, becoming the largest and most important town in Hungary. The population tripled; many new palaces, monasteries, mansions, and streets were built, and the city was the centre of social and cultural life of the region. Wolfgang Amadeus Mozart gave a concert in 1762 in the Pálffy Palace. Joseph Haydn performed in 1784 in the Grassalkovich Palace. Ludwig van Beethoven was a guest in 1796 in the Keglević Palace.
