The map depicts the evolution of Bell Hill Environmental Centre, from Bell Hill Farm, in 30 years.
By comparing the 1976 and 2006 maps of Bell Hill, certain developments are noteworthy. Overall, it is clear that radical transformations occurred in the farm over the period, and it was totally converted into an environmental center in 2006.
On the whole, in 2006, a multimedia room replaced the barn, which stored grain and other items, in 1976. In addition, a farmyard was demolished, and in its place, a recreation area was constructed. Towards the right side, the poultry area and cowsheds were transformed into student housing. Finally, we can observe that the agricultural machinery storage space at the upper left corner of the map has been converted into a vehicle parking lot. Probing further, the farmhouse in the bottom and roads in the bottom left of the map did not go through any changes.
