A castle has stood in Dobrovo since the 13th century, but it slowly fell into disrepair over the centuries. A new Renaissance building was built on this site at the beginning of the 17th century, which has remained relatively unchanged to this day and is considered one of the most beautiful castles in the Goriška region. Dobrovo Castle will enchant visitors at first glance with its imposing and distinctive appearance. Its ground plan is almost square, with symmetrically placed towers at the corners. The outer wall was likely built during the Second Venetian War (1615–1617) and converted into a portico after its end. One of the towers was converted into a chapel dedicated to St. Anthony of Padua. The chapel walls are decorated with hung originals and copies of Gothic frescoes from the northern Primorska region. The first owners are said to have been the Counts Colloredo, for a shorter period the Marquise Montecuccoli, and from the end of the 18th century the Catterini-Erzberg family from Gorizia. In 1872, ownership passed into the hands of the Baguer family following a wedding. On the first floor of the castle is the Knights' Hall, featuring the coats of arms of several noble families who owned the castle in the past. This hall contains a preserved mural depicting the naval attack on the city. Today, the Knights' Hall hosts numerous musical performances and other events. Also of interest is the Hunting Room, where the treasures of Count Baguer, painted on the walls by Clemente Del Neri in 1894, are displayed. His works of art can also be viewed in the stairwell.
