Ceremony Sites in Nassau

My fiance and I have just booked the Riviera at Massapequa for our reception in October 2010. We've agreed that we don't want to get married at the same location.

Does anyone have any ideas for an indoor ceremony elsewhere near Massapequa? We were both raised Catholic and are not opposed to getting married in a Catholic or non-denominational church. Any kind of old historic building would be considered too. Anything, really!

Thanks!
