It is quite an impressive structure and I'm glad I saw it but equally if you skipped it you wouldn't be missing anything of that much importance.
Also when I went there was lots of protests which made it hard to see in some ways but as it is in the middle of a very busy intersection it was easier to get close to because there was no traffic, just lots of people. Not sure if you can normally go inside of it but with all the protestors about I certainly couldn't.
