In 17th century, this is where an important small port on the Northern Kurzeme coast was established; at that time, Sīkrags was larger than the village of Mazirbe. Some think that the first church of Irbe congregation was located in Sīkrags, built in the second half of the 17th century. And the old cemetery standing on a hillock next to the former church location is still visible in the centre of the village.

Sīkrags bears the status of an urban construction monument of national significance since 1983. The protection zone covers the former village centre and the houses "Ķeļķi", "Jaunklāvi", "Kilāsidāmi", "Vīnamegi", "Baznīckalns" and "Vecvalki" ("Ķirškalni"). Nowadays, it is busy in summers, while during winter only some families live here permanently.
