This year's Open Monument Day will take place on Sunday, September 14. We are taking this opportunity to welcome the public to Platte Hunting Lodge, which is otherwise not open to the public.

The Platte Hunting Lodge will open on September 14, 2025 from 11:30 am to 3:30 pm. A free guided tour will be offered at 12:00 and 13:00. Admission to the house and the guided tours is free. It is not necessary to register for the guided tours. Those interested should meet in the castle rotunda on the first floor.

Once a year, always on the second Sunday in September, the whole of Germany goes on a discovery tour. Over 7,500 historical sites open their doors and inspire a large number of visitors. The "Open Monument Day" is the largest cultural event in Germany. Since 1993, it has been coordinated nationwide by the German Foundation for Monument Protection, which is under the patronage of the Federal President.

"A living monument ...". The Platte hunting lodge was built between 1822 and 1826 and was used as the autumn residence of the ducal family of Nassau during the hunting season. During the Second World War, it was destroyed down to the outer walls by an aerial bomb in the final days of the war. After decades of decay, the Stiftung Jagdschloss Platte e.V. foundation took over the building in 1987.

The foundation, which was formed from the Erich-Haub-Zais Foundation with the aim of preserving and rebuilding the castle ruins, rented the building to the spa facilities for marketing and operation from 2007 onwards. In September 2014, the Stiftung Jagdschloss Platte e.V. transferred the heritable building right granted in 1987 to the Wiesbaden trade fair, congress and tourism holding company TriWiCon with the handover of the castle. This fulfilled the purpose of the foundation.

Today, Wiesbaden Congress & Marketing GmbH, a subsidiary of TriWiCon, operates the Jagdschloss Platte, which is also used for wedding ceremonies, for example.
