Trinity Church is the oldest church in Manhattan. This of course was not the first church building the congregation worshiped in because the church was founded in 1697, and this building was dedicated in the spring of 1846.
The cemetery is so old that most of the grave stones are worn away so they are unreadable or even broken.
The second picture reminds me of the drip sand castles I used to build on the beach. I never realized I was building a historic style sand castle when I was little.
