Johanneskerk

Before the construction of the current church, there was a cow market on the site. In 1830, the Reformed Church was built here. This was expanded in 1868 with a transept. The church replaced the dilapidated St. Mauritius Church that belonged to the St. Mary's Monastery of the Carmelites. That church and the monastery were probably built in the 14th century and stood on the current cemetery on the Galamagracht in IJlst. The 16th century pulpit with baptismal fence, the board with the collection bags and the Bader pipework of the original organ were transferred from that church to the current Mauritius Church at the time.

Mennonite church with extensions. The church has a neck gable dated 1857; heavily framed entrance. On either side service buildings under a saddle roof with a shield in front and behind and chimneys above. Six-pane windows. Cast iron fence along the church grounds. Pavement posts of the service buildings. Single manual organ, made in 1881 by Bakker and Timmenga.

Roman Catholic St. Joseph Church from 1876. Sober single-nave neo-Gothic cruciform church with front tower. One of the seven churches that architect Pierre Cuypers built in Friesland. Interior largely from the construction period of the church. The windows were made by F. Nicolas. Single-manual organ with free-standing console from 1904, made by Joh. Hilboesen (Amsterdam).
