Overview
- Public access resumes this weekend with a free open day on Saturday and a festive service on Sunday attended by Culture Minister Wolfram Weimer, Berlin Mayor Kai Wegner and Georg Friedrich Prince of Prussia.
- The overhaul introduces climate control, a redesigned visitor route, step‑free access via a new elevator and an interactive area with a 3D crypt model and touchscreens.
- The 1,400‑square‑meter crypt contains 91 coffins spanning five centuries, making it one of Europe’s largest dynastic burial sites.
- Final costs total roughly €29–29.5 million, with about €9.3 million from the cathedral parish and additional support from the federal government and the state of Berlin.
- Expenses exceeded early estimates by about €12 million due to a pandemic‑era start, higher construction and energy prices linked to the war in Ukraine and a longer build time.
