As with all good museums, the connection of the spaces enables either a prescribed route to be followed – perhaps a timeline or similar – or one of choice, where you can jump from one exhibition to another, dependant on your own interests, revisit bits you have missed, want to see again or are part of a specific education or research programme.
The introduction of the connecting ramp is an important design element in this regard. It acts as a processional route and is part of the museum narrative. It also plays a role in the architectural experience in terms of kinaesthetic. The back of the knee is one of the most sensitive parts of the body in imprinting a pleasurable spatial experience (the other being the back of the neck).
The movement required up or down the ramp accentuates this physical aspect of memory. The ramp and the gallery balconies also enable a different perspective of some of the larger exhibits (particularly for children), offering elevated views from different levels.
The open and transparent atrium space that faces out on to a new plaza and facing the historic railway (physical and intellectual engagement with both subject and history) also acts as threshold and transition from one world to another.
