Templ palace in Mladá Boleslav, Gothic palace in Mladá Boleslav, Czech Republic.

Templ palace is a three-storey late Gothic building at Krajířova 102/4 in Mladá Boleslav, built on a stone base on the western slope of the sandstone spur above the Jizera. Its rendered stone walls end in a massive saddle roof, and a small garden lies along the south side. It is a cultural monument.

The palace was built between 1488 and 1502 for Jan Císař of Hliník, who became the first captain administering the combined Mladá Boleslav, Michalovice and Bezděz estates. In 1886 the Regional Museum Society acquired it and installed exhibitions from 1887 to 1910. After 1918 it was adapted as a prayer house for the Czechoslovak Hussite Church; neglected under communism, part of its roof collapsed in 1977, after which it was repaired with public funds.

The name Templ comes from an unsubstantiated legend linking the building to Jan I of Michalovice and the Knights Templar; it only became common in the 19th century. From 1887 the Regional Museum Society installed its exhibitions here, and after 1918 the building was adapted as a prayer house of the Czechoslovak Hussite Church.

The palace stands at Krajířova 102/4, just off Staroměstské náměstí, on the western slope above the Jizera. Its three floors step down the slope, so the entrance level and the garden on the south side sit at different heights. The building is used for public cultural and social events rather than as a museum.

The name Templ rests on an unsubstantiated legend: it was said to come from Jan I of Michalovice, a magnate of King Wenceslaus II, who supposedly built it through a connection with the Knights Templar. The name only caught on generally in the 19th century.
