Some Interesting Buildings in Luanda

I spotted the tin building the other day and got the chance to photograph it yesterday after dropping a colleague off.

It is situated a couple of blocks inland behind the Banco Nacionale (the fantastic pink building with the dome on the Marginal (sea front).

I have no idea what it was for, the style looks colonial, but not Portuguese. French perhaps?

Apart from some missing pieces, it does not seem to have been trashed too badly, and there were security guards sitting in it, so presumably someone has plans for renovating it.
