Santa Sofia. After the arrival of the Order of Saint John in 1530, the knights settled in Birgu, where part of Fort St Angelo was used as a palace for the Grand Master. The knights themselves lived in auberges, but these were more large houses rather than palaces. When the Order began to build a new capital Valletta in 1566, a new Grandmaster's Palace and a series of new auberges were built. The auberges in Valletta are much larger than their counterparts in Birgu, and can be considered as palaces. The most important auberge still standing is Auberge de Castille, which currently houses the Office of the Prime Minister of Malta. Over the years, the Grand Masters also built a number of large residences in the countryside, such as Verdala Palace and San Anton Palace. Both of these now serve as official residences of the President of Malta. The Archbishop of Malta has a palace in Mdina. The inquisitor also had a palace in Birgu and another in Girgenti until the abolition of the inquisition in 1798. The nobility, upper classes and individual knights of the Order built a number of private palaces, especially in Valletta, but also in the countryside. There are other palaces built by the nobility, such as, most notably Palazzo Parisio in Valletta and Palazzo Dragonara in St Julians. Poland The former Kingdom of Poland, known as the Polish–Lithuanian Commonwealth, once spanned over , which allowed the nobles to construct their residences anywhere from modern-day Poland to as far as southern Estonia. The Polish aristocracy (szlachta) greatly favoured Baroque and Rococo architecture of the period. Most notable architect specializing in those styles was Dutch-born Tylman van Gameren (also Tylman Gamerski), who designed several renowned palaces, for both kings and nobles, throughout the Commonwealth. Tylman also left behind a lifelong legacy of buildings that are regarded as gems of Polish Baroque architecture. His most famous works include Krasiński Palace and Łazienki Palace, both in Warsaw, and Branicki Palace in Białystok. Other palatial architects in Poland at the time were Chrystian Piotr Aigner, Szymon Bogumił Zug, Domenico Merlini and Johann Christian Schuch. At present, Poland possesses hundreds of varied-style palaces and residences designed by architects from all over the world. Some best examples are Wilanów Palace, Presidential Palace, Oliwa Abbot's Palace, Copper-Roof Palace, Palace of the Ministry of Revenues and Treasury, Rogalin, Jabłonowski Palace, Zamoyski Palace in Kozłówka,
