22 giant sculptures are on display from 25 March to 5 June in the heart of San Marino medieval city.
Lupan, Wrekon and Strapper are members of the Mutoid Waste Company, a performance art group born in the UK during the 80s, famous for building giant welded sculptures from waste materials.
An app has been launched that will make it easier to enjoy the exhibition, as works are spread throughout the old town centre.
