One of the grandest sweeps of architecture in Florence, the Pitti Palace was built in the 15th century. Its gallery includes a huge collection of paintings dating from the 15th to 17th century, and occupying the whole left wing of the first floor, one of the most significant groups of works is by Titian and Raphael. You’ll also see important works by Rubens, including the Four Philosophers and the Allegory of War, and pieces by Caravaggio and Velazquez. In fact, there are over 500 works on show in all.
And it’s not just canvases that you’ll see; the Palatine Gallery is also known for its frescoes. Laid out according to the personal tastes of its collectors from the House of Medici, rather than by painting school or by chronological order, the gallery has been open to visitors since the day Leopold I of Lorraine opened it back in 1828. There is also a cafe in the courtyard of the Pitti Palace.
