The land on which the Presidential Mansion was built was, until the final decades of the nineteenth century, outside city limits. The eastern limit of the town was the Royal Palace. Beyond that, there were fields and small farms. The only buildings appearing on the maps of the period were the manor of the
Duchess of Plaisance (known as "Ilissia" and today housing the
Byzantine Museum) and the
Petraki Monastery, both built in country areas far from the centre of town. The limited significance of the area at the time may be revealed by the fact that a girl's orphanage (which no longer exists) was built there in 1854. Furthermore, the land along
Kifissias Avenue (now named
Vasilissis Sofias Avenue) also remained unbuilt and was reserved by the state for the construction of ministry buildings. In early 1870 the state allowed the sale of land to private individuals which resulted in the construction of mansions to house the wealthy families of
Athens. About 1890, the architect
Ernst Ziller was entrusted with the construction of the Crown Prince's Palace. This palace later became the residence of the royal family and is used now as the Presidential Mansion. During modern times, with the city of Athens extending over many square miles, the Presidential Mansion is located near the centre of the capital next to the
National Garden and Parliament.
Herodou Attikou Street, where the mansion is located, is not only one of the most beautiful roads in the city but is also bound to the political and social life of Greece, as also situated there is the
Maximos Mansion where the
prime minister of Greece has his official office. The Presidential Mansion with its garden occupies a total area of about 27,000 square metres (about 7 acres). The official entrance to the mansion is on
Herodou Attikou Street. == Design and construction ==
