While the stunning ancient architecture is the city's strongest draw, travelers should also take in buildings like the baroque St. Paulinkirche (St. Paulin's Church) and the Liebfrauenkirche (Church of Our Beloved Lady), Germany's oldest Gothic church. Trier's expansive Kurfürstliche Palais (Electoral Palace) built as a "wing" to the "Basilika", is considered one of the finest examples of Rococo style in Germany, and its Baroque Palastgarten (Palace Gardens) are a peaceful green oasis in the middle of the city. Another popular attraction is the Karl Marx Haus (Karl Marx House) birthplace and museum.
