Mariella Frostrup's heaven on earth

The broadcaster doesn't normally advocate spending hours walking around old buildings - but makes an exception for the temples of Angkor in Cambodia.

The most extraordinary place I've visited is the 12th-century temple complex at Angkor Wat, completely inaccessible during Cambodia's troubled past but very easy to get to now - it's just an hour's flight from Bangkok.

I'm no great advocate of wandering around old buildings - I'm fine for about an hour but then I get a bit bored - but for Angkor Wat I make an exception.

The main temple is like a mini-Versailles and there's another one you have to visit very early in the morning because the sun lights up the many Buddhas' faces at dawn - it's one of the most spectacular things you'll ever see.

Then there's a temple where the trees seem to have grown out of the walls, one of many beautifully strange sights here. If you go, be sure to make an early start - it's worth it, just to see the complex in all its glory. It's just the most remarkable place.
