Beautiful Churches on Long Island (2/21/09 update - scroll down)

I have mentioned before that the Church I was married in - St. Martin of Tours in Amityville - is one of the most beautiful Churches in the DRVC. I keep meaning to take some pictures of the Church and post them to show why I believe this.
I would like to know if anyone else knows of beautiful parish Churches on Long Island. Please let me know!

12/14 UPDATE - moved to top, From the comments we have:

St. Kilian's, Farmingdale (yes!)
St. Patrick's Bay Shore
St. Aloysius, Great Neck
St. Agnes, Rockville Centre


I have not been to St. Patrick's or St. Aloysius so I will have to check them out. St. Agnes, I am not sure of, the outside is beautiful, but the inside is kinda plain?

12/21 UPDATE from the comments -

Infant Jesus, Port Jefferson
St. Patrick's, Glen Cove (the oldest parish in the DRVC)
St. Ignatius, Hicksville
Cure of Ars, Merrick
St. Isidore, Riverhead
St. Joseph's, Garden City
Sacred Hearts Jesus and Mary, Southampton

I would also add St. Therese of Liseux in Montauk and St. Raphael's in East Meadow, which are both newer Churches.

2/21/09 Update -

I have been to Mass at St. Patrick's in Bay Shore, and it does have a very nice sanctuary. Unfortunately, the sanctuary is not used as they have moved the altar to almost the middle of the Church, I suppose in an effort to allow more people to see the priest. (This actually doesn't work at least from I sat, it was hard to see the priest and the lector). I went to an evening Mass so it was dark and I would have liked to see the Church with sunlight streaming through the stained glass windows in the high dome in the center of the Church. The Church is similiar to St. Joseph's in Babylon and has a very old feel to it.

I also attended a lecture at St. Joseph's in Garden City and peeked into the Church before the lecture started. It was very beautiful with a big baldachino (?) over the altar. I will have to get there for Mass some day.
