Built on a mountain summit, Hohlandsbourg Castle offers a magnificent all-round panorama over the plain of Alsace and the Vosges Mountains. In clement weather, you can even make out the spire of Strasbourg Cathedral and the Swiss Alps. This garrison stronghold built in the 13th century was the seat of the Lords of Habsburg. Measuring 100 m long and 60 m wide, this is the largest fortified castle in Alsace. Over the past years, the castle has been completely restored. Today, it is a centre for culture, exchange and sharing with several events staged in this superb green setting from 1st Saturday of April to the 2nd Sunday of November.
