There used to be a simple chain separating the public area in Arch One from the "off-limits" section by the entrances to the two Museum workshops. This week, we've installed a pair of swing-gates.
We didn't want boring old normal gates, and someone suggested designing them to look like the gates on a railway level crossing, to go with the "station" theme of the Museum Shop area. So that's what we did. And they're cool.
