The renovation increased the site’s green space by 1.5 times and created a new park of more than 6,000 sqm, complete with a café, gift shop, and community areas.

The project introduced new entry points, including a striking staircase on the eastern side, and added viewing terraces offering panoramic views of the capital.

A major feature of the renewal is the 1,700 sqm exhibition located in the western gun tower, which presents key moments of Hungarian history and struggles for freedom.

The restoration also uncovered significant archaeological finds, including remains of an 1815 observatory, a rare World War I anti‑aircraft gun mount, and coins and ceramics from Celtic, Roman, and Ottoman periods.

The Citadella will celebrate its reopening with a three‑day program from March 29-31, during which the exhibition will be free with prior registration.
