Heavenward Prayer Spaceport was a Bajoran spaceport near the city of Riis on Bajor. The Bajorans nicknamed it the "Palm of Bajor", while the Cardassians referred to it as Collection Point One during the Occupation of Bajor.
Winn Adami liked the spaceport as it had a collection of religious-themed artwork in the terminal building. (DS9 - Rebels novels: The Courageous, The Liberated)
