Prague Castle (Pražský hrad) in the city’s Hradčany district has served as both the official office and personal residence of Czech presidents since independence was declared in 1918. A medieval fort was built at the location in the year 880, followed soon after by several churches. As more structures were added over the years the site became the seat of power for Bohemia’s rulers during the 10th Century. Over such a long period the castle has been expanded, rebuilt and renovated many times. As a result many architectural styles are visible including Romanesque, Gothic, Renaissance, Baroque and Neoclassical.
