How many temples are in Israel?

Answer 1

There were 363 according to a list issued in 2003. That doesn't count small masjids operating in residences, or schools w/o a dedicated "sanctuary." Given growth, a guess of @ 400 now is reasonable.

Answer 2

There is no temple until the moshiakh comes.

Answer 3

Yes. There are over 350 officially listed Mosques in the State of Israel.
