Splendid modernist testimony, the Carlo IV was designed by Austrian architect Wölf. The néo-Renaissance facade recalls the National Theater and the National Museum. Its first resident was the Czech Savings and Loan Bank, demonstrated by the inscription HYPOTECNI BANKA CESKA on the exterior.
During the communist regime it became the central seat of the Czechoslovakian Postal Service. After years of neglect, thanks to the restructuration and restoration work of architects Maurizio Papiri, Adam D. Tihany and Simone Micheli, today it represents one of the most renowned 5 Star Luxury Hotels of Prague.
Traces of the old bank have found a counterpart in the interventions of contemporary style, created with the use of metal and glass, giving the spaces a luminosity. In the rooms, the bed headboards are original, dating to the first half of the XIX Century, as are some tablets, decorated with period frescoes, all masterfully restored.
