The manor house, built around 1840 from the Bonifacy Machnicki Foundation, is a single-storey building with a classicist four-column portico on the garden side. It was built on the foundations of an older building whose basement with a barrel vault has survived. It was taken over by the city in 1970, and the Cultural Centre opened its doors after the completion of renovations in the manor house and the neighbouring classicist buildings of the former St Martin's orphanage, St Blaise's Hospital, and the Convent of the Daughters of Charity of St Vincent à Paulo.

The museum of the interior designer and painter Władysław Wołkowski was set up through the efforts of the Olkusz Region Lovers Association. The collection is dedicated to the life and work of an artist specialising in wicker products. The artist himself arranged the exhibition in 1970. It includes objects made of wicker, reed, wood and string: furniture, baskets, platters, tapestries, portraits and landscapes, Slavic deities and figures from legends, compositions dedicated to events in Polish history, and sketches, drawings and notes.

The Africanist collection includes Dr Bogdan Szczygieł's collection, gathered during his stays in Africa asdonations from Poles working with him and from Mr and Mrs Kubarski. There are arts and crafts of African tribes, everyday objects, sculptures, ceremonial masks, textiles, jewellery, paintings, musical instruments, weapons, costumes and toys.

The mineral collection consists of examples of zinc and lead ores and associated minerals from the Olkusz mines and Jurassic fossils.
