The historic town centre is well preserved and is protected by law as an urban monument zone.

In the 17th century, the adjective spálené (i.e. 'burnt') was added to the name because of many large fires that damaged the town.

The eastern part of the municipal territory extends into the Brdy Highlands and includes the highest point of Spálené Poříčí, the hill Trokavecká skála at 706 m (2,316 ft) above sea level.

In 1620, during the Thirty Years' War, Poříčí was burned by the army of Charles Bonaventure Bucquoy.

[4] In 1749, the Metropolitan Chapter at Saint Vitus in Prague bought Spálené Poříčí.

The town remained in its possession until modern times, and the chapter still owns the castle today.
