Prague. Views from Petřín Lookout Tower (seen bottom right).

“The Petřín Lookout Tower (Czech: Petřínská rozhledna) is a 63.5-metre-tall steel-framework tower in Prague, which strongly resembles the Eiffel Tower. The Petřínská rozhledna was built in 1891 and was used as an observation tower as well as a transmission tower. The two observation platforms are accessible via 299 stairs in sections of 13 per flight running around the inside of the structure.”
