The two maps, as they are put together, show how Grange Park now is different from it was in 1920.

In 1920, visitors could enter the park from either the Arnold Avenue entrance or the Eldon Street one and would see a fountain in the park’s center. West of the fountain was a musical stage, and on the north and south sides of the stage were rose gardens with seats in the vicinity. Visitorswould see another rose garden in the east, by the Arnold Avenue entrance, a pond for aquatic plants in the northwestern corner, and a glasshouse by the Eldon Street entrance with seats nearby. 

[注意：“visitor视角”写法并不意味着抛弃描述方位，“第三视角”是“描述东南西北”的补充。]

Now, the fountain is gone, and now there is a square rose garden with seats on its four sides. Second, the musical stage is upgraded to an amphitheater for concerts. In addition, visitors entering from Arnold Avenue will see a café and a children’s playground in the corner on their left, and if patrons enter from Eldon Street, they will see a water feature on their right. It is also notable that there is an underground car park near the water feature.

Clearly, the park has changed immensely.
