Burg Arras, Medieval castle and heritage museum in Alf, Germany.

Burg Arras is a medieval castle perched on a rocky spur above the Mosel Valley near Alf, Germany. It features thick stone walls, several towers, and vaulted interior rooms, and today the complex houses a museum, a hotel, and a restaurant.

The castle was founded in 936 on the site of an earlier Roman fort, making it one of the older fortifications in the Mosel Valley. French troops destroyed it in the 17th century, and the rebuilding that followed gave the structure the form it has today.

The name Arras comes from a Latin term meaning "at the rock," a reference to the cliff on which the castle stands. Inside, the museum rooms display Roman-era objects found locally, giving a concrete sense of how long this spot has been in use.

The path up to the castle is steep, so sturdy shoes are a good idea, and the cobblestone courtyard inside also requires some care when walking. Guided tours are offered by the operators, and an entry fee applies for the museum section.

Burg Arras is the only castle along the entire Mosel River that operates at the same time as a hotel, restaurant, and museum. Guests who stay the night sleep inside rooms built from medieval stone, surrounded by actual exhibition pieces.
