What sacred buildings do jehova witnesses have?

We have so called "Kingdom Halls" where we do regular congregational meetings 5 times a week.

A bigger one is called the "Assembly Halls" where different congregations meet during Special, Circuit and District Assemblies, all are being held annually.

There is also these publication houses called "Bethel" where all our publications are published.

Our main office is located at Brooklyn, New York just beside the Brooklyn bridge we call our Watchtower Headquarters.
