At the height of the Hanseatic League, when Stockholm had strong trade links with Germany, many German merchants settled in this area of Gamla Stan. They originally worshipped at the monastery on what is now Riddarholmen, but moved to St Gertrude's guildhouse after its expansion in the 1580s. Baroque renovations in 1638-42 gave the German Church its present appearance; its tower was rebuilt after a fire in 1878. Tessin the Elder designed the royal pews, and Jost Henner created the richly decorated ornaments and figures on the portal. The church is best viewed from Tyska Brinken, where the tower rises up 96m (315ft) from the narrow street. At the church's summer concerts you can listen to a replica of a 17th-century organ, constructed for the church in 2004 at a cost of ten million kronor.
