The village was first mentioned in 1424 as "Ubba Ffockema up den Zyldyck", and means sluice and dike. In 1272, a sluice was built at the site in the newly poldered land around 't Zandt. In 1317, a dike was built northwards towards Uithuizermeeden.[3] In 1444, the land to the east of Zijldijk was poldered and the sluice became obsolete.[4]
Zijldijk has three churches. The Mennonite church was built in 1772 in a non conspicuous barn-like building. It is still in use as a church. The Dutch Reformed church has been reconstructed as a village house. The Reformed Church was constructed in 1886, and nowadays serves as a care facility.[4][5]
