Havelock Square is one of a couple of public parks around the historic part of Central. Havelock square is a bit different though as it is an unfenced park with a one way paved road going around it. Havelock Square was part of The Grey Institute Grant originally surveyed in 1856, with the oldest houses being built in 1862. The Holy Trinity Church on the eastern side of the square was built in 1866 and re- built in 1897 after being destroyed by a fire, while the St Johns Methodist Church on the western side was opened in 1894.
The yellow building with the green roof in the background of the photo is the Havelock Conference Centre which offers a great conferencing option with accommodation. (I'm giving them a quick punt cause I have a friend who works there and I got some of the above information off their website.)
Havelock Square is situated on the Donkin Heritage Trail and is a stone's throw away from some of Central's best know historic sites as well as the restaurants in Parliament Street.
