Comparing pictures: Wembley Stadium

Both pictures show the Wembley Stadium (London), but the first picture shows the old one and the second picture shows the new stadium.
They are both located in the same place, but the first stadium was built in 1923 and the second one in 2007. Another thing that they've got in common is that they're greyish. The shape of the old stadium is oval but the new one is round. Another difference between them is that the building of the second picture is more modern that the building in the first photo. The place in picture 1 had a capacity of 100,000 and the place in picture 2 has a capacity of 90,000. 
In the first building were celebrated many historic football matches and concerts.
