The picture above was taken from the stop at Park Station (or Park Halt as it was known) which was in the vicinity of Joubert Park. It’s looking south west with the old Synagogue also in view. There is a picture in the post taken from the opposite side to put it in perspective.
The tower became a municipal office and the square became a collection of corrugated iron structures known as ‘Tin Temple’ which served as municipal offices until City Hall was built in 1915. The tower and tin temples were demolished in the 1930s. Plein Square is south of Johannesburg Station. When traveling north up Rissik Street toward Braamfontein, it’s the open park on your right before reaching the bridge that crosses the railway lines.
