There are around 1,300 Christians in the Gaza Strip and the number of Christians is steadily declining. Gaza's Christian community mostly lives within the city, especially in areas neighbouring the three main churches: Church of Saint Porphyrius, The Holy Family Catholic Parish in Zeitoun Street, and the Gaza Baptist Church, in addition to an Anglican chapel in the Al-Ahli Al-Arabi Arab Evangelical Hospital. Saint Porphyrius is an Orthodox Church that dates back to the 12th century. Gaza Baptist Church is the city's only Evangelical Church; it lies close to the Legislative Council (parliamentary building). Christians in Gaza freely practice their religion. They also may observe all the religious holidays in accordance with the Christian calendars followed by their churches.
