The illustrations depict changes to a museum building and grounds in 1957 and 2007. Overall, the building became much larger and the number of trees was greatly reduced.
Looking first at the grounds of the museum, as shown at the bottom of the map, all the trees were removed from the roadside, and also most of them to the left and to the rear of the museum were cut down. The driveway leading up to the museum was removed and a car park was built by the roadside.
In terms of the building itself, the entrance was moved from the middle of the building to the left-hand side of the building, where a new museum shop was built. To the right, the local history room was turned into a reception area. Further to the right, the museum storage room was replaced by a café. Above the café, the National History exhibition room was turned into a local history room. This room leads into two new rooms that were constructed, which are a special exhibitions room and an education centre.
