The old town area of Thun mainly arose in the 12th century, when Berchtold V of Zähringen built Thun Castle and extended the city around today’s Hauptgasse.
The unique high pavements that characterise the upper part of the Hauptgasse are worth a visit for their unique architecture alone. Quaint boutiques, trendy shops, upmarket shops and trendy bars also invite you to browse, stroll and look around.
