Why is the pool at Buckingham Palace a secret?

So this exterior photo that Chris pulls up, it's honestly a little hard to describe, but I'm gonna give it a shot. I see lots of Corinthian columns, many windows, most capped with these beautiful stone triangular pediments. Honestly, it's a little similar to the building style you see in Washington, D.C. 's monuments. It's just significantly more impressive. Yeah, it's a massive palace.
