Open Monument Day in Potsdam

Open Monument Day — Germany's Largest Cultural Day

Open Monument Day is Germany's largest cultural day. Since 1993, thousands of monuments across Germany have opened their doors free of charge on the second Sunday in September each year. The day is coordinated by the German Foundation for Monument Protection (DSD). Millions of people participate in Germany alone every year. In Potsdam — the city with the highest density of monuments in Brandenburg — the day is an event of its own magnitude. Over 50 monuments are participating.

2026 Motto: “NetzWERKE: Denkmale & Infrastruktur"

The national motto for 2026 focuses on the connection between monuments and the infrastructural world that surrounds them: water pipes, railways, roads, power grids, telegraphs. How were palaces, industrial buildings, or residential houses integrated into larger supply networks? How did water supply, heating, and lighting work in an 18th-century facility? How are the palaces of Sanssouci, the Belvedere, or the park's pumping stations actually connected? The motto allows for a systemic view of the monuments — not just as individual objects, but as nodes in networks.

SPSG Participation — Rarely Accessible Objects

The Prussian Palaces and Gardens Foundation Berlin-Brandenburg (SPSG) is the custodian of Potsdam's famous palace landscape. On Open Monument Day, it opens rarely accessible objects: the Norman Tower on the Ruinenberg — an artificial ruin serving as a viewing tower, accessible only a few days a year; the Belvedere on the Klausberg — a viewing structure built by Frederick the Great; and other ancillary buildings not usually open for visits. These objects are a real insider tip for monument enthusiasts.

What to Expect

The participating monuments offer guided tours, lectures, and children's programs — all free of charge. Plan your day in advance via the official Open Monument Day website or the Potsdam.de overview. The urban area is well connected by the S-Bahn S7 and tram lines; many palace grounds are also easily accessible on foot or by bike. A leisurely day of exploration is well worth it.
