The Städel Museum is one of the most important museums in Frankfurt. It is located in the Museumsufer (literally the Riva dei Musei, that is an area that concentrates a large number of museums within it). Inaugurated in 1817, the museum preserves an artistic collection that goes from antiquity to the present day. The origin of the museum derives from the collection of the Frankfurt merchant and banker Johann Friedrich Städel, who donated his rich collection to the city to make it a museum. Today, through donations and acquisitions, the museum has become an important point of reference for the artistic and cultural panorama of Frankfurt. Among the works in the collection there are names of artists such as Botticelli, Bronzino, Tiepolo, Tintoretto, Bacon, Braque, Carrà, Degas, Matisse, Monet, Picasso, Renoir, Severini, Sisley, Van Gogh, Rembrandt and several others. There are famous works of art history, such as the Madonna with Child and twelve angels by Fra Angelico, one of the three versions of the portrait of Julius II by Raphael and Vermeer's Geographer.
