15th Century Cathedral
The story is that a young boy by the name of Aeneas Sylvius Piccolomini, who was born in 1405 and grew up in this tiny town when it was called Corsignano, later became a known Humanist scholar and philosopher. Oh, yes, among his other credits, he also became Pope Pius II, thus accounting for the name change from Corsignano to Piensa in his honor. Pope Pius II, who was elected pope in 1458, tried to redesign his birthplace into a model Renaissance town – and he wanted to accomplish this in 3 years; alas his dreams were never completely fulfilled. You see, his architect was a crook and embezzled money, but because the Pope was pleased with the completion of the Cathedral and a couple of other buildings, he forgave the architect instead of boiling him in oil.
