The Horácká Multipurpose Arena in Jihlava unfolds into four distinct buildings, two of which already exist. Located on the border of Jihlava’s historical center, the arena—a structure usually confined to the periphery of cities—is adjacent to a park and university and places itself in the continuity of these two spaces. Rather than marking an interruption in the existing city structure, the arena serves as a transparent and fluid transition between seemingly distinct spaces, thereby reviving and opening up the area to new functions, and ultimately extending the city center beyond its strict historical bounds. The peaks of the façade segments visually reference both the Gothic verticality of the historic center and the red hedgehog symbol from the city’s coat of arms. On the roof rests an outdoor track, further enriching the building’s sports functionality and inviting audiences to look upon the surrounding views of the city.
