Between 1966-1968, a hall underpass designed by architects Josef Kaleš, Jiří Konrád, Albert Pišl and Jaroslav Strašil was built in the centre of Prague's Wenceslas Square, under the main crossroads. Architect Milada Obersteinová, then working at the Centre for the Development of the Trade Network (SROS), designed the interiors of the perfumery and stationery shops.
