The St. Hilarion Monastery was revealed at the Tal Um Amer site, identified as the historical location of Tabaitha mentioned on the sixth-century map of Madaba and in classical sources. The site was discovered in 1991, and excavations were conducted by the Palestinian Department of Antiquities in collaboration with the French Biblical School over several seasons between 1996 and 2023. The excavations revealed the remains of a large monastery from the Byzantine and early Islamic periods, consisting of two churches, a baptismal hall, a reception area, as well as monastery facilities, including a dining hall, wells, a clay oven, drainage networks, and a cemetery. The building was paved with stone tiles and mosaic floors, featuring Greek inscriptions mentioning the name of St. Hilarion, the founder of monasticism in Palestine. The monastery was equipped with a hostel for pilgrims and a large bathhouse with rooms for cold, warm, and hot water to serve pilgrims and travelers. The site holds exceptional value due to its association with St. Hilarion, the founder of monasticism in Palestine. Hilarion was born in the city of Tabaitha near Gaza in 291 AD. He studied in Alexandria and was greatly influenced by the Egyptian saint Anthony. At the age of 15, in 306 AD, he returned to Gaza, where he gained fame. In 329 AD, Hilarion founded the first monastery in Palestine. During the persecution of Christians in the era of Emperor Julian (361-363 AD), Hilarion migrated to Cyprus, where he passed away in 371 AD. Saint Hesychius later transferred his remains to Gaza. Saint Jerome wrote his biography in 390 AD. St. Hilarion is venerated in the Eastern Orthodox and Roman Catholic Churches, and rituals honoring him are observed in Europe, especially in Italy, Cyprus, and Sicily. His feast day is celebrated in Cyprus on October 21 each year. The site was placed on the tentative list of UNESCO World Heritage Sites in 2005 as a cultural site, preparing for official inscription on the World Heritage List.
