On the northern edge of Prague Castle, the horticultural gardens are located. They encompass the area of about four hectares and all the products of the gardens are used by the Office of the President.
One half of the gardens was originally the area of the pheasantry founded in the 16th century by the emperor Rudolf II. Now there is an orchard there with an apiary from the times of the first Czechoslovak president Tomáš Garrigue Masaryk. It was designed by the Slovenian architect Jože Plečnik and bees are kept there today still. Not far from the apiary, there stands also the presidential villa. Built in the 19th century, since 2005 it serves as the residence of the head of state. In the other half of the gardens, there are greenhouses which supply, among other things, also the flower decorations of the representative areas of the Castle for example during state visits. It has become a tradition that the public can enter the horticultural gardens once a year during the vine festival in September.
