For those who don't know it, the original entrance gatehouse for the Rice Lane zoo is still there, right next to the plough on Rice Lane.
Here's a couple of photo's I took back in 2011, when the Plough was still shut. It's been reopened for a couple of years now.
In the first photo, you can see the gatehouse, it's the single storey building with the curved roof on the imediate left of the picture.
In the second picture, you can clearly see the relief above the doorway with birds, and monkeys in the detail.
