Endale Arch, also known as Enterdale Arch, is located under East Drive, slightly south of the Grand Army Plaza entrance on the north side of the park, and adjacent to the northeast side of Long Meadow. It was one of the first two arches to be completed, in 1868. Its exterior contained interspersed yellow Ohio sandstone and red New Jersey brownstone. The interior was composed of brick set between alternately black and yellow wooden stripes, designed as such to prevent condensation from dripping downward. Endale Arch contained seats underneath it, but these were later removed. In 2014, the Prospect Park Alliance began a five-year restoration of the arch, which was completed in 2020.
