Muzeum Militariów we Wrocławiu, Military artifacts museum in Arsenal building, Wrocław, Poland.

Muzeum Militariów we Wrocławiu occupies two wings of the Arsenał Miejski (Mikołajski Arsenal) at Cieszyńskiego 9, a Gothic building from 1459 with an irregular quadrilateral plan around an inner courtyard. Exhibitions spread over three floors. The exterior is almost devoid of ornament, while the interiors show timber structures resembling Silesian granaries.

The Arsenal was built in 1459 and is one of the few medieval buildings in Wrocław preserved in its entirety. It served as the city's weapons depot, and today it houses three institutions: the Archaeological Museum, the Military Museum and the Building Archive. The museum occupies two wings of the building, with exhibitions on three floors.

The museum's name comes from the Latin militaria, and its displays follow Polish arms from the 18th century onward. In the white-weapons room, each saber, broadsword or cutlass is paired with photographs showing similar weapons in insurgents' hands, starting with the January Uprising. A 1925 painting by Wojciech Kossak, "Battle of Kircholm", hangs among the blades.

The museum occupies two wings of the Arsenal at Cieszyńskiego 9, with displays on three floors; the Archaeological Museum and the Building Archive share the same complex. The inner courtyard, with two towers and a 1620 draw well, is used by artists and theatre groups, so it can be busy. Enter from Cieszyńskiego Street and allow time to climb between floors.

One room holds one of Europe's largest collections of military helmets, a display that often catches visitors off guard. These helmets come from different countries and time periods, showing the range of warfare technology.
