Escuan, there are so many weaknesses in this puzzle, both conceptually and practically; reading, if you have the patience, all the comments on this thread will give you a flavour.
I don't send in my entries, but did de-construct the grid to make something with both the building and city appearing in just one vertical line (apart from 'The', which Dryden earlier questioned).
The consensus is that L and S can both be on the ground (which demonstrates nothing, because the observer doesn't know at what time each object came to be on the ground; or that L & S can be in mid-air, equal distances below their dropping points. There are various obstacles here too, in that one of the objects seems then bound to obscure existing contents of a cell.
All the cells are used as part of the building, the name of the building, the place of the building, and objects which were probably never thrown off the building. And that's all there is...
