Industrial Gas Museum

It's fascinating to follow the walking route that runs through the old Technopolis in Gazi, in operation from 1862 until 1984. The preserved furnaces and industrial buildings from the mid-19th century appear like giant art installations. Photos and interactive elements provide an idea of what the works were like when in operation. Head up the watchtower of the New Watergas building for a panoramic city view. The site is often hosts music and other events and there's a cafe.
