This is just a piece of grass with benches in front of a the council house. There is no reason to visit and I have no idea why this is rated as an attraction. This is something which you will see on your travels around Bristol, the council house is worth taking a photo of, if you are a tourist. It was made famous on the TV show Skins as an area which the kids hung out at on a Saturday afternoon because there is sod all for them to do in Bristol and they cannot drink in pubs. I had to sit here to eat my lunch whilst doing a course nearby last month on a Saturday, it was a hot day so the place was busy with people boozing and smoking. Visit only if you are a teen on the prowl for sex, drugs and booze but I am unsure if this is a successful way to mate cause I have not tried it. It's only other use is a place for people to protest cause it is outside the council house, although they did have a pop up crazy golf thing there a while ago.
