St. Nicholas Greek Orthodox Cathedral, a replica of St. Sophia Cathedral in Constantinople, is open daily to visitors and worshippers. The Shrine of St. Michael, a small chapel built by a Greek family in thanks for the miraculous cure of their young son, is open daily. If the church is open, you should see the 23 unique stained glass windows and the three massive Czech chandeliers. The sixty tons of Greek marble once graced the Greek exhibit at the first New York World's Fair.
