The story of Alma Park in Gelsenkirchen is one of change. A former working colliery is now home to Europe's largest indoor leisure park and a popular Ruhr region attraction.

Alma Colliery, which gave the park its name, was once one of the region's most productive coal mines. It opened in 1905 and operated until 1962. The mine was a major employer and played an important part in the economy and culture of Gelsenkirchen and the wider Ruhr region.

After the mine closed, the site stood empty for years and was eventually designated an industrial monument. In 2013, entrepreneurs Andreas Althoff, Jens Haltermann and Dirk Podubrin bought the site and transformed it into Alma Park.

Turning a colliery into a leisure park was an ambitious project. The new owners wanted to create a place for entertainment and shared experiences, with activities for different ages ranging from laser tag and paintball to trampolining and mini golf.

The transformation proved successful. The park now attracts more than 110,000 visitors a year, with more than ten activities, five live escape rooms and a food and drink area.

Alma Park has also become a meeting place for people from the region and further afield. Group visits, company events and parties give visitors opportunities to spend time together and create shared memories.

The story of Alma Park shows how a site can find a new purpose. A former colliery has become a lively leisure venue, combining ideas, commitment and creativity with a focus on bringing people together.

That story continues as the park develops and adds experiences. There is more to discover in the years ahead.
