Local and foreign tourist can explore the underground architecture and walk kilometers under the Prague’s city centre in historical basement. Groups of about 20 people will be guided by educated workers. Helmets and warm clothes will be available for anybody who will ask for it because the steady temperature in the basement is about 16 ˚C (60.8 ˚F). Other attractions might be the machine-room of the funicular in Petrin or the waterhouse in Podoli.
These attractions promising unusual experiences will become part of the offers of travel agencies and information bureaus where people can book them in the middle of this year. First people will probably enjoy these attractions this autumn.
