Museums
Beneath the market square of Olkusz — the town called the "silver town" — lie the undergrounds of the former capital of lead and silver mining. The route has two parts: under the Gothic town hall and under the County Office building, where the royal mint operated at the turn of the 16th and 17th centuries. They were discovered during the revitalisation of the market square in 2011; today's route is multimedia-based and accessible to strollers.
The town hall was built at the beginning of the 15th century from red Parczew conglomerate; it was one of the largest buildings of its kind in Poland at the time, larger than the town hall of Kraków. It was demolished in 1825, but the cellars survived, and material from the demolition was used to erect the County Office building.
On the route you will see more than 200 artefacts from some 90,000 finds: coins, ceramics, spurs and horseshoes, including items made of Olkusz lead. Under the County Office awaits a collection of coins, models of mining devices and the "silver hall", while children can try a clickable pickaxe with fun facts.
Mining was already operating here in the 11th century, and the first mention of Olkusz dates to 1257. In 1374 Elizabeth of Poland granted the first mining ordinance, and the coat of arms with a pickaxe is known from a seal of 1386. The royal mint of 1579 reportedly struck more than half of Polish coins of that period.
Entrances: Rynek 4 and the County Office building in the southern frontage of the market square. One ticket covers both routes: PLN 20 regular, PLN 15 reduced, audio guide PLN 7. Open Tue–Sun from 9 am to 6 pm; an app, audio guides and guides for groups are available.
