Where was the first roofed stadium?
From Research, Im not 100% sure its the first, but the oldest is
Bramall Lane, Sheffield, England. You my want to double check this
but I'm quite sure its the first, as it opened in 1855 as a cricket
ground.
The oldest football grounds in the world used to be the Drill
Field located in Northwich, Cheshire, England. They were the home
grounds of Northwich Victorica Football Club from 1874 until they
were demolished in 2002. They were regarded as the oldest by the
Football Association.
