When is a church like a ship?

Loads of people walk past this building and don't really pay attention to it...

It's the Willesden and St Marylebone Sea Cadet Corps...

The amazing thing about this building is that it's designed like a church, is corrogated iron and concrete blocks, it's listed, and the interior defies all imagination.

The interior of the building is laid out like the exterior of a ship! TS Bicester!

It's true - if you are passing and there's a fete or anything on do do do take the chance to pop in - it's Cambridge Road, just up from Kilburn Park Tube station...
