The current capacity stands at 41,623 and the ground has gone from being a huge oval shape to one with all four sides close to the pitch. There is almost no part of the current stadium that hasn't markedly changed in recent years with only the huge old Shed wall remaining of the original stadium - which can be seen opposite the Megastore and box office. 

As well as all the work on the stadium itself the whole 12.5 acre site has seen the building of two four-star hotels, three restaurants, conference and banqueting facilities, underground car park, health club, a music venue and business centre. It has come a long, long way since the original athletics venue was first opened in 1877.
