What is particularly interesting about No. 1 Riverside is that it became home to the Islamic Cultural Center of New York. The Center, which also owns the large mosque on Third Avenue and 96th Street on the Upper East Side, still maintains this townhouse as a smaller prayer center, despite having moved their major functions to the mosque in 1991. The new mosque, though very modern in design, seems to follow the conventions for a large mosque, including a domed central hall and a minaret. The townhouse by Giblert, in contrast, is an odd design, even for a temporary center. The limestone façade and typical Baroque ornamentation are not typical for any Islamic center.
