Al-Burj (Arabic: البرج) was a Palestinian Arab village 14 km east of Ramle close to the highway to Ramallah, which was depopulated in 1948. Its name, "the tower", is believed to be derived from the crusader castle, Castle Arnold, built on the site. Victorian visitors in the 19th century recorded seeing crusader ruins close to the village.

The name "al-Burj" is of Arabic origin, and means "The tower". The names refers to the site's Crusader keep.

A Byzantine lintel was found in the village in the 1870s, with "a Greek cross inscribed in a circle, and having its four arms ornamented with curious facet-work."

Charles Clearmont Ganneau suggested al-Burj as the site of the Castellum Arnoldi, near Beit Nuba, 'in primes auspices campestrum,' built in 1131 A.D. by the Patriarch of Jerusalem, to protect the approach to that city (William of Tyre).

Just west of Al-Burj is Kŭlảt et Tantûrah, "the castle of the peak." It is the remains of a tower, with 5-meter thick walls, and a door to the east. It is possible the Crusader castle called Tharenta, under Muslim rule since 1187.

While nearby Bayt Jiz often has been identified as the Crusader village of Gith, some scholars (Schmitt, 1980; Fischer, Isaac and Roll, 1996) have suggested that Gith was actually at Kŭlảt et Tantûrah.

In 1838 el-Burj was noted as a Muslim village, in the Ibn Humar area in the District of Er-Ramleh. It was also noted as a being small, "situated on an isolated hill surrounded by open vallies and plains." It was further noted that "there are here evident traces of an ancient site, apparently once fortified."

In 1863 Victor Guérin found the village to have no more than 200 inhabitants, and noted that the Crusader fortress was in ruins.
