I'm starting a new thread, rather than have this all-important topic get lost at the end of the "Is Athens Safe" thread. It's in response to the two posters who say, on that thread, that Athens isn't a beautiful city.
Athens is beautiful, if you know where to look and how to look. Despite the depredations of the speculative building boom of the 60s and 70s, there are still plenty of good neoclassical houses left, and many have been beautifully restored. All you have to do is look out for them - and look up, past the street- level shops.
The panoramic views of the city from the Acropolis, or from Lycabettos, or - most of all - from Philoppapos Hill, are stunning on a bright day, and simply incredible at sunset. The views of the Acropolis itself, from the Pnyx or Philoppapos, are heart-stopping.
And Athens is a GREEN city. The hills - Acropolis, Pynx, Philoppappos and Aereopagitos offer endless opportunities for walking in green spaces, beautifully landscaped and planted.
The grafitti, which the two posters mentioned, deserve a closer look. Some of them are excellent: skilled, witty, colourful, adding real interest to the concrete walls, and worth a closer look.
The vast improvements made in Athens during the last ten years - the metro, the pedestrianisation of huge areas, the wonderful archaeological park - have made it a very different city from the nefos-choked hell of the past.
