First, the Euljiro area downtown. Korea Bank can be seen near the middle at the intersection there.
The same area today:
You can see the same building there beneath all the tall buildings (and actually first looking at this image should help you find the same building in the 1951 image). It's now a museum.
Seoul Station:
The city was taken over three times during the war and there are some pretty poignant pictures at the War Memorial here as well showing snipers on the rooftop for example as it was a pretty good vantage point at the time. Now it looks like this:
That's the same building that has been maintained all this time, but at the same time a new station has been built just to the left (you can barely see it in the picture above) that looks like this:
That's where you can take the high-speed train (the KTX) and others to the rest of the country.
Getting on the train in 1951:
Getting on (and off) the train today:
The Chosun Hotel in 1951 (established in 1914):
And now:
Some street in the city, no idea where:
Some street in the city today:
People by the Han River in 1951:
People hanging out by the river today:
Namdaemun in 1951:
I wish I could say that this was Namdaemun today:
...but some nut burned it down. Now it looks like this:
You'll never guess why it was burned down. There was this 69-year-old guy that wasn't happy with the money he got from selling this land to developers...so as a protest he decided to burn the gate to the ground.
Han River in 1951 with mountains in the background:
Han River today:
This is a stream that flows through Seoul called the Cheonggyecheon:
This stream was actually covered by concrete later on, and then in 1968 a highway was built over top. The stream still flowed underneath though and in 2003 the mayor of Seoul (now the president) decided to restore it, and this was completed in 2005. Before 2005 this area (Euljiro 4-ga Station for example) was actually a pretty crappy neighborhood, with a lot of shops selling lighting and textiles and whatnot, and the raised highway overhead just added to the industrial feel. But now that the stream has been restored it looks like this:
and sometimes like this at night.
Kids playing on the street in 1951:
Kids playing on the street today:
These pint-sized arcade games on the street are positioned at just the right height for kids to sit down and play.
Finally, what appears to be a bit of hanging out amongst the ruins in 1951:
Compared to hanging out at the PC bang (pc room) today.
