The largest colonnade in Karlovy Vary, built of stone in the pseudo-Renaissance style, was opened in 1881 and covers a total of five mineral springs. The attic of the colonnade is complemented by allegorical statues representing the different months of the year. In the past, it was a laughing stock and earned various nicknames, such as the carrot bed.
