Take this and Take that

There are two towers (Beccati Questo and Beccati Quello) near Lake Chiusi on a piece of ground that is now only crossed by the Chiana canal: one is square and higher than the other which is partly buried in a marshy area. It is said that Ascanio della Cornia, lord of Castiglione del Lago, quarrelled with Pope Paul III about a question of boundaries. They took up arms but the clashes came to nothing. Things remained as they were, so the lord of Castiglione del Lago had fortifications and a tower built where the boundary of the two domains passed, writing to the pope, “Now take this if you can!” The pope was annoyed and immediately gave the order to build another tower opposite it and wrote in reply to Ascanio della Cornia, “And you take that if you can!”
This is a fictional version that is found in old texts. But the names speak for themselves, so there may be some truth in it. According to another version, the tower on the Chiusi side, dated 1279 (but completed in 1427) was supposed to have been built by the Guelph government of Siena after a victory to symbolise control over the marshlands which marked the boundary. Perugia felt the need to build another one to retaliate against Siena. What is certain is that the Sienese tower Beccati questo (“take this”) was submerged by the swamp after the streams and the lake were diverted by work carried out by the Papal State at the end of the 15th century. A third of the tower was buried by the reclamation fill which was necessary to stop advance of the swamp. As for the actual use, the two towers did not have defensive functions, but were simply “toll stations”, where the taxes were paid that were due for the transit of goods at a border point, which could be crossed over a bridge between Siena and Perugia.
