St. Martin, Gothic minor basilica in Amberg, Germany.

St. Martin is a three-aisled Gothic hall church on the south side of Amberg's market square, built from 1421 by the town's citizens. It measures 72 metres long and 27.8 metres wide, with a publicly accessible tower almost 92 metres high. A ring of 19 chapels surrounds the church, closed above by a shared gallery.

St. Martin replaced a three-aisled Romanesque basilica with three apses, a twin-tower facade and a choir tower that stood on the site of today's nave. From 1421 the citizens of Amberg built the present late Gothic hall church. Protestant services were held from 1544, and in 1557 Calvinists under Elector Ottheinrich removed side altars and images. After the Counter-Reformation the church was baroquified from 1628, and between 1869 and 1879 it was regothicised.

The name recalls Martin of Tours, the patron saint. The church holds the heart and entrails of Count Christian of Ortenburg (died 1684), buried separately from his body at his own request. The nine bronze bells date from the 14th to the 19th century; the oldest, cast on 24 July 1318, rings for Sunday services.

The 92-meter tower is open to visitors who climb to the observation platform for views across Amberg and the surrounding landscape. Those planning the tower ascent should be aware that the stairs are narrow and moderate fitness is helpful for the climb.

The wooden roof of the basilica spans 28 meters without intermediate supports, a revolutionary design for its construction period. This innovative engineering allowed the entire interior to remain unobstructed and open.
