King's Cross St Pancras tunnel

The new Pancras Square has been connected to King's Cross St Pancras underground station by a tunnel since July of last year. It is well hidden - so much so, that in fact, I've walked past the tunnel a couple of times without ever realising it was there. Not that I never needed to use the tunnel itself as it isn't exactly a short cut to anywhere particular interesting (unless you are a property developer/speculator).

Still, in a redevelopment that has thrown up its fair share of bland and uninteresting design, the tunnel is perhaps, along with the redesigned King's Cross Railway Station, worthy of a visit for anyone interested in architecture (or at least pretending they live in a Star Trek fantasyland). The 90m tunnel is equipped on one side with an integrated LED light wall which displays a radiating form of light show.

The entrance to the tunnel is at One Pancras Square building. It is located at Pancras Square, part of a massive redevelopment and gentrification of St Pancras & Somers Town district.
