The temple was originally a part of an extensive precinct of three courtyards and represented a fusion of ancient Syrian and Roman architectural styles. The temple's proportions and the capitals of its columns were Roman in inspiration, while the elements above the architrave and the side windows followed the Syrian tradition. The highly stylized acanthus patterns of the Corinthian orders also indicated an Egyptian influence. The temple had a six-column pronaos with traces of corbels and an interior which was modelled on the classical cella. The side walls were decorated with pilasters.
Inscription and dedication
An inscription written in Greek and Palmyrene, on the column bracket that supported the bust of the temple's benefactor, the Palmyrene official Male Agrippa, attested the temple was built in 131 AD. The inscription was dedicated by the Senate of Palmyra to honor Male Agrippa for building the temple, which was dedicated to Baalshamin, the Semitic god of the heavens, to commemorate the Roman Emperor Hadrian's visit to Palmyra around 129 AD. The translated inscription is:
Damage
Parts of the temple were damaged to some extent by bombings in 2013, during the Syrian Civil War. The southeastern corner of the temple wall was damaged further by looters who made two openings to steal the furniture of the adjacent guesthouse.
Destruction
In May 2015, Palmyra was captured by the Islamic State of Iraq and the Levant, a terrorist group with a history of destroying ancient religious structures. Shortly after, ISIL reportedly claimed that it did not intend to demolish the buildings at Palmyra's World Heritage Site, but stated that it would destroy any artifact it deemed "polytheistic" or "pagan". On 23 August 2015, ISIL militants detonated a large quantity of explosives inside the Temple of Baalshamin, completely destroying the building. The temple's destruction was announced by the head of the Syrian Directorate-General of Antiquities and Museums, Maamoun Abdulkarim. Photographs of the placement of the explosives, the explosion itself and the remnants of the temple subsequently appeared on social media. UNESCO described the willful destruction of the temple as a "war crime". The destruction was independently verified by a French Pléiades satellite, which photographed the pile of rubble a few days later. After the temple's destruction, the Institute for Digital Archaeology announced plans to establish a digital record of historical sites and artifacts threatened by IS advance. To accomplish this goal, the IDA, in collaboration with UNESCO, will deploy 5,000 3D cameras to partners in the Middle East. The cameras will be used to capture 3D scans of local ruins and relics. Following the recapture of Palmyra by the Syrian Army in March 2016, director of antiquities Maamoun Abdelkarim stated that the Temple of Baalsahamin, along with the Temple of Bel and the Monumental Arch, will be rebuilt using the surviving remains.
