Worth seeing is the St. Kastor Church, whose Romanesque tower was built around 1179; the early Gothic three-aisled staggered gallery hall church was built in the 2nd decade of the 14th century. In the church there are wall paintings from the 14th and 16th centuries, which were reconstructed in 1902, as well as a winged altar from around 1500 with figures of the patrons and panel paintings from the life of the Virgin Mary. During restoration and renovation work in the early 1990s, various graves were found in the church. In addition to various pieces of jewelry, a fragment of a scallop shell was also found. There is evidence of a pilgrim hostel on the church granary.
The medieval curtain wall is still largely preserved. Of the towers of the city fortifications, the gate tower and the leaning tower still stand; the latter leaned in the 19th and 20th centuries and was demolished by approx. 7.50 m in 1950. Stumps of 5 other towers have been preserved. Right next to the gate tower is the 1,100-year-old court oak tree with a chest height of 8.10 m (2014).[4]
The “Old Town Hall”, built in the late Gothic style in 1434, is considered the second oldest half-timbered town hall in Germany.
A half-timbered house from 1650 houses Dausenau's historic inn on the Lahn.
