Of strategic importance since it first straddled the Spree River in the 13th century, Berlin went on to hog centre stage in the turbulent twentieth. Today the city, restored as the nation's capital, is the focus of a mammoth project of reunification and the barometer of Germany's moods.

This is the heart of Germany, with a stoic beat that echoes through grand public buildings, glorious museums and theatres, urbane restaurants, bustling pubs and raucous nightclubs. The Wall is gone but Berlin is still divided: there's a distinct segue from the glitz of the west to shabby East Berlin.

When to go:
Berlin is a fascinating city year-round, although most visitors arrive between May and September when the weather is the most reliable. Things are busier in high season, but despite the crowds, summer is a lovely time to be here because much of life moves outdoors. Rain is, however, possible in any month, so come prepared. From November to early March, skies tend to be gloomy and the mercury often drops below freezing. On the plus side, there are fewer visitors and shorter queues. Avoid major holidays like Easter, Christmas and New Year and special events such as Loveparade - unless, of course, that's what brings you here in the first place. Content by Lonely Planet - Germany
