Burg Gudenau, Medieval castle in Wachtberg, Germany.

Burg Gudenau is a residential fortress in Wachtberg built around a four-winged structure with a roughly rectangular layout. The facades show Gothic bay windows and a round corner tower with a slate roof, while three other corner towers carry Baroque domes and a five-story gate tower marks the entrance to the outer courtyard.

The water castle was built in the early 13th century and was a fief of Altenahr Castle, held by the lords of Gudenau. Around 1560 the four-winged main castle was extended with a Gothic bay window and curved gables. In the 17th and 18th centuries the complex gained its present appearance, including Baroque roofs on three corner towers and a five-story gate tower with an octagonal clock turret.

The Baroque garden at this site follows Italian design principles and is one of the few surviving private Baroque gardens in the region. Walking its formal paths, visitors can still read the original layout of the planted areas and alleys.

The site is best visited in dry weather since the paths run through open gardens and courtyards. Wear comfortable shoes and plan enough time to move between the different parts of the complex at a relaxed pace.

The five-storey gate tower of the outer courtyard carries an octagonal clock turret with a slate hipped roof. The main castle's four round corner towers have mismatched roofs: one pointed slate spire and three Baroque-style roofs. The three-terraced garden is the only surviving private Baroque garden in the Rhineland.
