On Sunday, October 4, 2020, 25 Swiss castles invite you to the 5th National Castles Day. Their gates and drawbridges will then be open from 10 am to 5 pm for a varied program. So – come on in!

The association Wikimedia CH and the Swiss OpenStreetMap association (SOSM) will complement the event with a Swiss Fortresses Day 2020 (Burgentag 2020). Young and old medieval enthusiasts alike are invited to discover a castle ruin on their own. You decide the program yourself. Every castle has a history and many have something mystical about them. And there is often a fireplace nearby. Find out more with the following tips:

• Map with selected castle ruins sites (see picture below),
• A photo challenge to upload missing photos of castles.

The photo challenge is simple: Work through this list of castle objects without pictures and upload the photos to Wikimedia Commons! For each uploaded photo there is a tweet (from @trending_places) with the hashtag #CastleProject. The photo is then usually immediately visible on the Castles project map.

The interactive online map of selected castle ruins shows a hand-picked selection of castles in Switzerland that are freely accessible and easy to reach. Depending on the castle, it can be up to one kilometer (i.e. approx. 20 min.) or more away from the nearest public transport stop or parking lot. Please follow the signs and treat nature with respect (e.g. make sure that there is no danger of forest fires in the area, watch out for ticks, don’t leave litter).

The map contains only a small part of the castles and palaces as they are managed in the Castles Project Switzerland. The Castles project links open data directly from the four open data projects OpenStreetMap, Wikipedia, Wikidata and Wikimedia Commons (photos).

The Swiss Burgentag 2020 was initiated by the SOSM association and Wikimedia CH. The event is also kindly supported by the Swiss Castle Association. We thank the association ‘Die Schweizer Schlösser’ for agreeing to link the two action days Swiss Castles Day and Burgentag 2020.
