Not sure about this one, I think pyramids are supposed to have a base.

the base is the roof .. seen from below

Really original angle ..

The glass pyramid built in front of the Louvre, has no basis ....

This is quite original but it is also questionable...overall well done author!

very nice Entry... lolvy....

I agree...very nice! Great job!

Super cool great shot!

The smaller "towers" appear to be pyramids.

A pyramid (from Greek: "πυραμίς" – pyramis[1]) is a structure whose outer surfaces are triangular and converge at a single point. The base of a pyramid can be trilateral, quadrilateral, or any polygon shape, meaning that a pyramid has at least three triangular surfaces (at least four faces including the base). The square pyramid, with square base and four triangular outer surfaces, is a common version.
