The city's oldest section is “Gamla Stan” (Old Town), located on the original
small islands of the city's earliest settlements and still featuring the medieval
street layout. Some notable buildings of Gamla Stan are the large German Church (Tyska kyrkan) and several mansions and palaces: the Riddarhuset
(the House of Nobility), the Bonde Palace, the Tessin Palace and the Oxenstierna Palace.

The oldest building in Stockholm is the Riddarholmskyrkan from the late 13th century. After a fire in 1697 when the original medieval castle was destroyed, Stockholm Palace was erected in a baroque style. Storkyrkan Cathedral, the episcopal seat of the Bishop of Stockholm, stands next to the castle. It was founded in the 13th century but is clad in a baroque exterior dating to the 18th century.
