Annually during the last night of April many fires will be burning and people will celebrate the arrival of spring. The largest burning of witches´ celebration in the Czech Republic is happening at Ladronka Park in Prague. „Again this year we are planning a large cultural and sport program, competitions, workshops and relax zones with refreshments. But we are also preparing a surprise for all visitors. It is the famous Hogwart School of Witchcraft and Wizardry,“ says the major of Prague 6 Metropolitan District, Marie Kousalíková. In the school that will be set up by the technician station of the children´s house (DDM), kids can try out various magical activities. In the astronomical tower along with professor Triloni they can tell fortunes from their own colour pictures; in the playground they can play quidditch with madam Hooch and professor Snape will make his own „potion”. On top they can print their photos alike the wanted refugee prisoner from Azkaban or just peek in the greenhouse of professor Sprout full of mandrakes and devil´s toils.
