What is arguably Budapest's finest museum opened in 1906 in the presence of Emperor Franz Josef. Flanking Heroes' Square, with the Műcsarnok (Hall of Art) on its other side, it was built near the end of a building boom during which many of the city's greatest buildings were constructed. Despite its classical appearance, the museum is one of the country's most forward thinking. It was the first in Hungary to organize blockbuster exhibitions, bringing with them long lines and media publicity. The museum is Hungary's main repository of foreign art, and it is especially renowned for its collection of old master paintings—there is way too much here to attempt to see in one or even a few visits. The collection of 3,000 works includes pieces by Giotto, Tiepolo, Tintoretto, Veronese, Titian, Raphael, Van Dyck, Rembrandt, Rubens, Hals, Hogarth, Dürer, Cranach, and Holbein. The Spanish collection, one of the most significant of its kind, holds paintings from El Greco, Vélazquez, and Goya. One major highlight among the Dutch paintings is The Sermon of St. John the Baptist, by Pieter Bruegel the Elder. The museum got its start based on the donation of a personal portrait collection from Count Széchenyi, and was significantly enlarged in 1871 with pieces from the Esterházy family, an enormously wealthy noble family during the Austro-Hungarian empire. The museum puts much effort into its docent program, through which it provides a thorough training in art history. The docents offer free one-hour guided tours in English (and other languages) Tuesday through Friday at 11am and 2pm, and Saturday at 11am. They rotate galleries with each tour. Before you leave, set aside a little time to admire the elaborate beaux arts–style building itself, which has a main facade with three classical Greek temples connected by colonnades. There are also Corinthian columns and in the pediment a sculpture of the Battle of the Lapiths and the Centaurs from the Temple of Zeus at Olympia.
