This is how i remember the rovers ground, i first went about 1957, shafts end (open terrace) Borough rd (covered terrace) Prenton pub end (covered terrace) Mersey clipper and car park side had a stand that was painted green and was about a house height, in front of that was a standing area called the paddock. In cost, the stands were the most expensive, then the paddock and then the rest of the ground was the same, the cow sheds was the Prenton pub end, that end if my memory serves me right had a series of apex roofs, the Borough Rd side had a flat sloping roof.
Spot on!
The Borough Road side was uncovered terracing for a while, after the war damage, until it was re-roofed in 1955. By the 1980s, this roof was itself dilapidated, although new corrugated metal cladding of the rear of the terrace at least smartened the appearance from outside the ground. A TV gantry was also erected above the roof in the 1980s.
One thing I have just found out, from reading The Complete Record Book, was that when the existing Prenton Park was opened in 1912, Rovers brought with them their existing stand from the 1st Prenton Park (which was located where the school is, across Prenton Road West), and this was re-erected on the Borough Road side of the new ground. However, it was destroyed by high winds on New Years Day 1916, and as far as I am aware, that side of the ground was subsequently terracing only, until the whole ground was redeveloped into an all-seater stadium in the 1990s.
