По крайней мере,так считается...



Farmhouse built making use of a Roman arch

Malborghetto means evil small hamlet: it does not sound very reassuring: the name given to this building is most likely due to the fact that travellers, who stopped here on the last leg of the journey to Rome, were often robbed. The lower part of the building shows the neat design of Roman masonry, while the upper one is a medieval addition made with stones. The building which was used as a tower, a farmhouse and a coach station was originally built as a triumphal arch dedicated to Emperor Constantine. The emperor started here the final battle against his rival Maxentius: the battle ended at Ponte Milvio where his enemy fell into the river and was drowned.

В античном Риме эту башенку изготовили из аккуратного кирпича,а в темные Средние Века ее верхушку достроили,грубо накидав камней с раствором.
