Its not particularly unusual to see buildings getting knocked down. There are a couple on Capital Bye-Pass that some guys have been working on recently.
But this one was, I thought, rather old, and perhaps even historic. I think there is a picture of this house in the Architecture Tour. I guess this is not surprising that it was knocked down, but sort of puts into focus that there is no Historic Preservation or other listed restrictions here. Not that World Monuments Fund or UNESCO has Monrovia's settler heritage in its sights (which is probably a hot-button issue, anyway). But, should it?
