the Landwehrkanal. Meanwhile, country peasantry were generally not welcome in the city, and so the gates also served to restrict access. However, the country folk were permitted to set up trading posts of their own just outside the gates, and the Potsdam Gate especially. It was hoped that this would encourage development of all the country lanes into proper roads; in turn it was hoped that these would emulate Parisian boulevards—broad, straight and magnificent, but the main intention was to enable troops to be moved quickly. Thus Potsdamer Platz was off and running. It was not called that until 8 July 1831, but the area outside the Potsdam Gate began to develop in the early 19th century as a district of quiet villas, for as Berlin became even more congested, many of its richer citizens moved outside the customs wall and built spacious new homes around the trading post, along the newly developing boulevards, and around the southern edge of the Tiergarten. The development was piecemeal, but in 1828 this area just to the west of Potsdamer Platz, sandwiched between the Tiergarten and the north bank of the future Landwehrkanal, received royal approval for a more purposeful metamorphosis into a residential colony of the affluent, gradually filling with palatial houses and villas. These became the homes of civil servants, officers, bankers, artists and politicians among others, and earned the area the nickname "Millionaires' Quarter" although its official designation was Friedrichvorstadt (Friedrich's Suburb), or the Tiergartenviertel (Tiergarten Quarter). Many of the properties in the neighborhood were the work of architect Georg Friedrich Heinrich Hitzig (1811–81), a pupil of Schinkel who also built the original "English Embassy" in Leipziger Platz, where the vast Wertheim department store would stand, although Friedrichvorstadt's focal point and most notable building was the work of another architect—and another pupil of Schinkel. The Matthiaskirche (St. Matthew's Church), built in 1844–6, was an Italian Romanesque-style building in alternating bands of red and yellow brick, and designed by Friedrich August Stüler (1800–65). This church, one of fewer than half a dozen surviving pre-World War II buildings in the entire area, forms the centrepiece of today's Kulturforum (Cultural Forum). Meanwhile, many of the Huguenots fleeing religious persecution in France, and their descendants, had also been living around the trading post and cultivating local fields. Noticing that traffic queues often built up at the Potsdam Gate due to delays in making the
