Burgruine Mödling
The castle was built at the beginning of the 11th century. In the early 13th century, the poet Walther von der Vogelweide visited the castle, which was then the residence of a side-line of the Babenbergers. It sustained heavy damage during the first Turkish siege of Vienna in 1529, and was completely burned down following a lightning strike in 1556; since then it has lain in ruins. The castle is a popular hiking destination for locals.
Schwarzer Turm
An artificial ruined castle from the early 19th century.
Karner St. Pantaleon
This round, late Romanesque ossuary was built in the 12th and 13th centuries, while Baroque bell tower and onion-domed roof were added in the late 17th century. Particularly notable are the fine carvings around the main entrance. The interior of the building was once richly decorated with Romanesque frescoes which during later centuries were completely covered by whitewash and other paintings; through careful restoration work however fragments of several of the original frescoes have been preserved.
Burg Liechtenstein
Located on the southern fringe of the Vienna Woods (Wienerwald), the castle was first built in the 12th century and besieged twice by Ottoman forces; it sustained heavy damage during the Russian occupation following WWII. The castle is owned by the ruling family of Liechtenstein. The castle is open by tour only (in German and English); tours last 40-50 minutes and begin at the top of the hour.
Spitalskirche
A late Gothic church built in the mid-15th century next to a former hospital (hence the name), noted for its spacious interior vault.
Othmarkirche
The foundations of this fortified church date back to the 12th century; following successive attacks by the Magyars and Ottomans the church has been rebuilt a number of times, with the current structure dating to the late Gothic period. The Baroque roof is one of the largest surviving timbre roofs in Austria.
