for the coronation at Prague Castle of Emperor Leopold II as King of Bohemia in 1791. The alterations included the addition of the palace's panoramic balconies. Despite the various alterations made through the years, remnants of original 16th-century murals and graffito work can still be seen in both of the interior courtyards. The Lobkowicz Collection The oldest and largest privately owned art collection in the Czech Republic, the Lobkowicz Collection draws its significance from its comprehensive nature, reflecting the cultural, social, political and economic life of Central Europe for over seven centuries. In 1907, Max Dvořák, a prominent member of the Vienna School of Art History, created the first complete catalogue of the Collections. After the restitution laws in the early 1990s, the Lobkowicz family was able to reassemble most of the collection, subsequently making it available to the public for the first time. Paintings The Lobkowicz Collections comprise approximately 1,500 paintings, including famous works by artists including Pieter Brueghel the Elder, Pieter Brueghel the Younger, Jan Brueghel the Elder, Bellotto, Lucas Cranach the Elder, Lucas Cranach the Younger, Diego Velázquez, Peter Paul Rubens, Paolo Veronese and Canaletto. The collections also include: an extensive collection of Spanish portraits; Central European portraits by Hans von Aachen and the School of Prague; Dutch, Flemish and German genre paintings; and over 50 paintings and watercolors of Lobkowicz residences by Carl Robert Croll. The three most prestigious artworks in the collection are The Hay Harvest (1565) by Pieter Brueghel the Elder, and two panoramic views of London by Canaletto. Other notable works include: Hygieia Nourishing the Sacred Serpent (c. 1614) by the Flemish master, Peter Paul Rubens; The Virgin and Child with Saints Barbara and Catherine (c. 1520) by Lucas Cranach the Elder; Christ and the Woman Taken in Adultery (c. 1530) by Lucas Cranach the Younger; Caritas Romana (early-mid 16th century) by Georg Pencz and smaller paintings such as A Village in Winter (c. 1600) by Pieter Brueghel the Younger and St. Martin Dividing his Cloak (1611) by Jan Brueghel the Elder. Venetian painting of the 16th century is represented by Paolo Veronese's David with the Head of Goliath (1575). The Italian baroque collection includes a prayerful Madonna by Giovanni Battista Salvi, and paintings by Francesco del Cairo, Antonio Zanchi and Giovanni Paolo Pannini. The principal Lobkowicz residences and estates—Roudnice nad Labem, Nelahozeves, Jezeří and Bílina—are depicted in oils and watercolors, commissioned from
