The Ylostins was a Frisian castle or a so-called stins in the city of IJlst, Friesland, Netherlands History It is not clear whether the city of IJlst gave its name to the Ylostins, or whether it was the other way around. The Harinxma thoe IJlst family founded the Ylostins in the Middle Ages, probably around 1400. After the family, the castle was also called Harinxmastins. The Ylostins was on the south side of the city. Together with the church on the north side, it formed a defensible complex. The owner of the Ylostins was also the “eeheer or olderman” of IJlst. The Ylostins consisted of a detached residential tower with bartizans at the top, with an U-shaped residential building next to it. The tower was additionally crowned with a hipped roof with decorative weather vanes. There also seem to have been painted windows, probably by the couple Tiete and Bernardina van Galama. If this is correct, then these windows may have been made by Julius van Galama, who married in IJlst in 1670. The last remains of the Ylostins were demolished in 1778. In terms of shape, the stins had great similarities with the Gruytermastins in Sneek. The residential center for the elderly in IJlst is named after the castle: 'Nij Ylostins'.
