Plaka is the old historical neighborhood of Athens, clustered around the northern and eastern slopes of the Acropolis, and incorporating labyrinthine streets and neoclassical architecture; modern Plaka has been built on top of the residential areas of the ancient town of Athens and it is known as the 'Neighbourhood of the Gods' because of its proximity to the Acropolis and its many archaeological sites. The old town is a very popular gathering place for travellers and tourists, particularly in the warm Athens evenings. Strolling the narrow streets of the Plaka flanked by ancient monuments, Byzantine churches and mosques, stately mansions, and inviting tavernas with vine-covered courtyards, makes a pleasant diversion. The Ancient Agora is a central feature of this area and the modern Plaka was built around it. Archaeological excavations have been taking place here continuously since 19th century and new ruins and artefacts are still being found. No cars are allowed in Plaka, which is completely pedestrianised. There is some great shopping to be done in the area but on busy days beware of pick-pockets who target market places and tourists. A visit to Athens is not complete without a long supper beneath the stars in Plaka.
