Some of the most interesting up-and-coming areas of Athens – Thissío, Gázi, Keramikós and Roúf – lie to the west of the centre, where the recent extension of Metro line 3 has acted as a further spur to the pace of change. Nightlife and restaurants are the chief attractions here, but there’s also a cluster of new museums and galleries. Here too is Kerameikos, site of a substantial section of the walls of ancient Athens and an important burial ground. South of Thissío, things are rather more traditional. The hills of the Pnyx and Filopáppou offer a pleasant, green escape from the city as well as fine views down over the Acropolis and Agora. On the west side of the hills, the residential zone of Áno Petrálona is a real delight, entirely untouristy, with some excellent tavernas and a great open-air cinema, though absolutely nothing in the way of sights.
