Made out of ice, an impressive life-size replica of the ancient Odeon of Herodes Atticus theatre is on display at the 37th Harbin International Ice and Snow Sculpture Festival in China.
The festival in Harbin, a city in China's north-east Heilongjiang province, is one of the biggest of its kind.
The event includes an ice snow sculpture expo and competitions, skiing, ice hockey, ice football, sledding, winter swimming, speed skating, and many other activities.
This is the first time a Greek monument has been constructed as part of the festival. The initiative was undertaken by the Greek National Tourism Organization (GNTO) in China.
To build the frozen city, tens of thousands of ice blocks were prised out of the kilometre-wide frozen river Songhua.
Other icons carved at this year's festival include Beijing's Temple of Heaven and Moscow's Saint Basil Cathedral.
The elaborate ice structures are also lit up at night.
The 37th Harbin International Ice and Snow Sculpture Festival runs until 25 February 2021.
It was built between 160 and 174 AD by the immensely wealthy Herodes Atticus, a philosopher from an old Athenian family, in memory of his wife Regilla.
A typical Roman odeon, large and exceptionally well-appointed, it was primarily used as a music venue.
The Odeon was destroyed in 267 BC at the incursion of the Heruli (or Erils), who burnt and flattened many buildings in ancient Athens; it was never reconstructed contrary to other edifices that suffered damages.
The monument was restored during 1952-1953 using marble from the Dionysus area; since 1957 it stages art festivals (concerts, ancient drama performances, etc.) mostly in the framework of the Athens Festival.
