The outdoor area on the site of the former sports ground was created in 2009 as part of the Muzeum Keltů in Dobšice. The replica Celtic oppidum doubles as a children's playground - oak timber play elements evoke a defensive rampart, palisade and entrance gate. The site also includes a semi-subterranean dwelling (polozemnice) reconstructed to its actual size of 3 × 5 m, based on a find from nearby Křinec. The area is freely accessible year-round.
