culture old and new in ultramodern Seoul

I'm just back from six days in Seoul - a city I liked enormously. It's full of juxtapositions and incongruities that make it fascinating. Here are just 2. The first is in downtown Seoul, but its name escapes me. Ancient monument of some sort, modern skyscraper.

The second is a Buddhist temple that was just across the road from the COEX exhibition centre where our conference was, and one of the few old things in an otherwise relentlessly modern (and consequently not so appealing, although there was some spectacular architecture on display) glass and concrete part of town.

Last is the recently reclaimed Chonggyechon, an inner city stream that used to be covered by a road. Quite an improvement. It's a popular haunt of courting couples - a frequent sight throughout the city.
