Sankt Stephan, Gothic parish church in Braunau am Inn, Austria

Sankt Stephan is a late Gothic parish church built from 1439 to 1466 to designs by Stephan Krumenauer, with a nave 60 m long, 25 m wide and 20 m high. Its 87 m tower, begun in 1492 by Wolfgang Wiesinger, carries a baroque onion dome added in 1759. The church follows the Landshut building school, and its ground plan shows the influence of Landshut's Martinskirche.

Construction began in 1439 on the site of an earlier chapel and was completed in 1466, when Braunau was an important trading center. The completion marked a period of growth for the town.

The church is dedicated to Saint Stephen, the first martyr. Its chapels were funded by the town's craft guilds, and the bakers' chapel with its late 15th-century winged altarpiece is the best known. The Renaissance choir stalls of 1598 were reserved for the mayor, council and guild masters.

The tower's 87 m height was confirmed by the Braunau survey office; older figures of 96 or 99 m stem from a 19th-century calculation error still repeated in some church guides. The main nave reaches 20 m, and the church is 60 m long without the tower. Entry is through the west portal on Kirchenplatz.

The tower is often wrongly called Austria's third-highest church spire; the three tallest are St. Stephen's Cathedral in Vienna, the New Cathedral in Linz and the Herz-Jesu-Kirche in Graz. Its height is also frequently given as 96 or 99 metres, a figure traced to a 19th-century calculation error; the Braunau survey office puts it at 87 metres.
