I've been familiar with the 4th Ave. IND station for over twenty years, but until this week, I had no idea that it was on the National Register of Historic Places. It was built in the 1930's, & got its spot on the list fairly recently, in 2005. To be honest, I found the place fairly depressing for a number of years, but over time - the thousands of early mornings standing on the platform - I've grown to find it extraordinarily beautiful. Being at an above ground station is a fine way to start the day, & the light up there is really something.
