The beginnings of the settlement of the town of Frýdlant date back to the 6th century AD. The first to settle the town were fishermen and hunters from Lužice. An important road led through Frýdlant, so a watchtower was built on a basalt rock, called Indica. Later it was rebuilt into a castle.
The first written note on Frýdlant dates back to 1278 when the Biberstein family bought the local castle from the Czech king. The history of Frýdlant is also connected with the name of Albrecht of Waldstein. Albrecht had his residence in Jičín, but he advanced to the title of Duke of Frýdlant.
The historical center of Frýdlant was declared a historical town reserve. The town's dominant feature is the castle with a beautiful interior and rich collections. Frýdlant also attracts visitors thanks to various untraditional cultural events, such as the Frýdlant Jazz Workshop or special Waldstein Feast. The beautiful landscape around Frýdlant is ideal for romantic walks and Frýdlant is also a starting point for excursions to the Jizera Mountains.
