Landmark on Main Street, located on Main Street in Port Washington is a cultural arts theater. It is in an old historic building that was renovated to use for the Arts as a non profit. What a great place to have in small town USA! I have seen amazing concerts there, this year alone: ranging from Ian Anderson, New Riders of the Purple Sage, Darlene Love, Paul Reiser, David Bromberg, Andrea Markovicci For one of the shows, I had injured my knee and couldn’t walk easily. The staff went out of their way to make sure I was able to access a seat with a cane. I am so grateful to them for making an aisle seat happen for me. Every show gets better and better! Can’t beat Landmark anywhere else on Long Island! Parking can be found on the street and across the street at the Library. There are about 40 seats in the balcony and another 350 in the orchestra. Every seat is comfy and gives a wonderful view of the very large stage.
