my favorite places on earth - Brunalleschi chapel.

Othervise known as Pazzi Chapel, it is located next to the Basilica di Santa Croce in Florence.

From wikipedia :

Pazzi were a noble Tuscan family, particularly notable in the medieval and Renaissance periods. In 1342 they gave up their titles of nobility so that members could be elected to public office. Their main trade during the 15th century was banking. Members of the family were in the Pazzi conspiracy to assassinate Giuliano de' Medici and his brother Lorenzo de' Medici on 26 April 1478. Andrea de' Pazzi was the patron of the chapter-house for the Franciscan community at the Basilica of Santa Croce, Florence, the Pazzi Chapel.

Oh, don't you love a conspiracy tale?!?!
