There used to be a concrete maze in my neighbourhood. It was about 6m x 4m. It was the best place to play hide-and-seek and catching. There was also a mini rock-climbing wall at the area. After school, we would not want to go to those plastic playground, but rather, these "playgrounds" made of natural elements like stone. Felt more real.
