Abu Mena, also known as Abu Mina, was a town, monastery, and important place for Christian pilgrimages in ancient Egypt. It is located about 50 kilometers southwest of Alexandria, near the city of New Borg El Arab. The site was named a World Heritage Site in 1979 because of its significance in early Christianity. Although few structures remain standing, the foundations of major buildings, such as a large basilica, are still visible.

Recent farming activities in the area have raised the groundwater level, causing some buildings at the site to collapse or become unstable. Because of this, the site was added to the List of World Heritage in Danger in 2001. It was removed from the list in 2025. To protect the most vulnerable buildings, officials placed sand under their bases to help stabilize them.

History

Menas of Alexandria was martyred in the late 3rd or early 4th century. Later accounts from the 5th century and beyond describe different stories about his burial and the founding of his church. The main details are that his body was taken from Alexandria on a camel, which was led into the desert beyond Lake Mareotis. At some point, the camel stopped walking, even when people tried to encourage it to move. This was seen as a sign from God, and the people who accompanied the body buried it there.

Most stories say the location of the tomb was forgotten until a local shepherd discovered it by chance. According to the Ethiopian Synaxarium (translated by E.A.W. Budge), the shepherd was believed to have healing powers. The text mentions that Emperor Constantine I sent his sick daughter to the shepherd, and she found Menas’ body. After this, Constantine ordered the construction of a church at the site. Some versions of the story mention a different emperor, Zeno, but archaeologists believe the church was built in the late 4th century. By the late 4th century, the site, called Martyroupolis, became an important place for Christian pilgrimages, where people sought healing and miracles.

Small terracotta containers called Menas flasks were sold to pilgrims as holders for holy water or oil. These items are found widely across the Western Mediterranean and date to about 150 years before the Muslim conquests. Though simple in design, they often have images of Menas, which are important for studying religious art. It is believed these flasks were made in the city where the church stood.

During the reign of Emperor Arcadius, the local bishop noticed that the small church could not handle the large crowds visiting the site. He wrote to the eastern emperor, who ordered the church to be expanded. This was the first of three major expansions that would happen over time. By the end of Late Antiquity, Abu Mena had become Egypt’s most important pilgrimage site.

In the mid-6th century, a port town named Philoxenite was built on the southern shore of Lake Mareotis to support pilgrims traveling to Abu Mena. Built on the ruins of a Roman settlement, the town had rest houses for pilgrims to stay before continuing their journey. It is believed that Philoxenos, a powerful figure in Byzantine politics, funded its construction.

Abu Mena was destroyed during the early Muslim conquests in the mid-7th century.

Archaeological excavations

The site was first studied from 1905 to 1907. These efforts revealed a large basilica church, a nearby church that may have held the saint's remains, and Roman baths.

A later, long-term series of studies by the DAI ended in 1998. The most recent work uncovered a large dormitory for poor pilgrims, with separate sections for men and for women and children. A complex located to the south of the great basilica was likely the home of the hegoumenos, or abbot. Studies suggest that the great xenodocheion, a reception area for pilgrims, may have originally been a cemetery. A baptistery, next to the original church, seems to have gone through at least three stages of development. Also found was a group of wine presses, including underground storage rooms, dating to the 6th and 7th centuries.

Threats

The site of Abu Mena was added to UNESCO's World Heritage in Danger list in 2001 because rising water levels near the area threatened the ancient ruins. This increase in water was caused by farming projects that aimed to make the land usable for agriculture. The soil around the site is made of hard clay, which is strong and can support buildings when it is dry. However, when the soil becomes wet, it weakens and causes structures, such as cisterns, to collapse. As the ground sinks, large empty spaces form under the ruins.

To protect the site, workers filled the bases of important buildings with sand and blocked the public from entering. To reduce the water pressure, the Supreme Council of Antiquities spent 45 million dollars digging ditches and installing pumps. A fence was also built to stop people from moving too close to the area. These efforts worked, and the site was removed from UNESCO's list in 2009.

Since then, water levels have continued to rise, damaging the ruins. The site was added to UNESCO's list again in 2025. In 2018, experts identified several problems affecting the site, including nearby housing, poor management practices, and water issues.

Conservation

Recent conservation efforts at Abu Mena include the use of better drainage systems and programs that involve the local community to address problems caused by rising water levels and other challenges. The Egyptian government used emergency plans to fix the rising water problem, but it does not have a complete plan to manage the site. Since UNESCO requires a management plan for all cultural and natural sites, several ideas have been suggested. The most dependable solution is to use a smart, sustainable membrane. This membrane is designed to improve airflow, energy use, and water control at the site. The plan includes building a dome-shaped covering made of a special material. This dome would provide the right amount of airflow, which is needed for all world heritage sites. The dome would also generate its own energy using solar panels on its outside layer. Additionally, the membrane would include a system that removes water from the air to help protect the site.
