Pot of gold at the end of the rainbow

Look, I know everyone is all worked up about the Netanyahu speech in Congress, scheduled for a couple of hours from now. But as I've said, what with being a senior civil servant and all I'm not allowed to talk about live political matters, so I'm not going to say anything about that today.

Instead, here's a picture I took recently of a rainbow over Jerusalem.

As we all know, at the end of every rainbow sits a pot of gold. Care to have a second look as to where that might be?

I understand the perspective is a wee bit unusual, but I assure you that tallish building at the end of the rainbow is... the Holyland tower.

I report. You figure out the significance.
