Banská Štiavnica is an exhibition hall of historical monuments. This hall includes also an Old Cheatau, which is a kind of stone chronicle of this mining town. The Old Cheatau is located above the Square of St. Trinity, while it is one of the oldest monuments of the town of Banska Štiavnica.

The Old Cheatau used to be a church, but it was rebuilt into a fortress during the Turkish threat. The dominant feature of the chateau is the originally Gothic castle tower with an underpass. Part of the Old Cheatau area is the St. Michael's Chapel, which has an above-ground and underground part, where the unground bones selected when digging new graves were inserted.

The Old Cheatau offers several permanent exhibitions for visitors:

• Archaeological exposition “Miners are coming…”
• From the history of Banská Štiavnica
• Model of altar of Master M.S. from 1506
• Shooting targets and historical weapons
• Baroque sculpture
• Lapidarium
• Reliefs and sculptures from Baroque Banská Štiavnica Calvary
• Himmelreich
• Smoking workshop

The Old Cheatau is administered by the Slovak Mining Museum and is open all year round. It is closed to the public during special events.
