Rivalling St. Stephen's in fame and importance, this royal church dates back to the Middle Ages
A 14th-century Gothic Landmark Near Buda Castle
Built during the reign of Béla IV between the 13th and 14th century, this royal church was modified several times - most notably in 1470 when King Matthias had its southern tower extensively renovated (it was named after him in the 19th century) and for the last time in the late 19th century. Matthias and other royals were wed here, such as Habsburg Austro-Hungarian emperor Franz Josef I of Austria, and Charles IV of Hungary was also crowned here following World War I. Interior highlights include its stained-glass windows, frescoes and impressive acoustics (it's a very popular venue for organ and other classical music concerts). There's also a museum displaying a wealth of ecclesiastical art.
