Clarion Congress Hotel Olomouc celebrates first anniversary of its opening. The Clarion, the 9th hotel of its brand operated by CPI Hotels, opened its gates to the first guests in September 2013. Its full operation was preceded by more than a 2-year complete reconstruction of the Sigma Hotel during which the hotel was rebuilt into a 4-star standard of the Clarion brand with its 126 rooms, congress facilities for up to 1,400 delegates, restaurant Benada and a wellness centre.
