The date of construction and original use of Għajn Żnuber Tower is not known.
It was suggested that the structure was a militia watchtower built by the Università while Malta was under the rule of the Order of St. John, but its location does not feature on any lists of militia watch posts, and the structure does not look like it was built for defence purposes.

It is now believed that the structure was a farmstead or a hunting lodge, which was probably constructed sometime during the 19th century.
The structure was modified extensively sometime before 1902.

The turret is known to have been used as an anti-smuggling post during the 19th century.
It was also used as a lookout post by the Northern Infantry Brigade during World War II.
The building was abandoned after the war, and it fell in disrepair and was subsequently vandalized.
