The Galleria Borghese in Rome, an exclusive gallery housed in an opulent palace, requires visitors to reserve a two-hour visit in advance. It features a significant collection of masterpieces by artists like Bernini, Raphael, and Caravaggio, and was reopened in 1997 after extensive restoration. Originally built for Cardinal Scipione Borghese in the early 17th century, the gallery reflects his passion for art and collecting.
