H.H. Cyriacus en Franciscus / Koepelkerk

The Lutheran community in Hoorn actually dates back to 1628. Johannes Vyand(t), a German minister who had fled, held the first meeting for the Lutheran inhabitants of the city on 1 October of that year in the bakery of a certain Gerbrand on the Hanekamsteeg. A number of times after that, a space in the Munt was also rented for this purpose. On 15 October of the same year, the community was officially founded. From that time on, a building called 'De Roosenobel' was rented near the Noorderkerk. Soon, problems arose between the minister and the elders, which led to dismissal. Vyand(t), however, continued to preach on his own initiative, and this degenerated into a schism within the young community. The newly appointed minister soon also came into conflict with the church council. In 1632, a piece of land on the Tempelsteeg was purchased for fl. 1700, and construction of a church began. When the number of members increased, this church space was expanded with galleries in 1645. Halfway through the next century, there was an urgent need for a new church building, as the old church had become very dilapidated and the number of parishioners was increasing. Insoluble conflicts between the then minister and a number of church council members and the inability to secure the finances delayed the construction of the new church for years. During the term of office of Isaac Scholten (1766-1778), the plans for the new building were however revived. Various plans had been submitted regarding the architecture. Ultimately, the design by Jacob Hart dating from 1761 was chosen. The work was accepted on 1 April 1768 for fl. 20,300. The old church was demolished. On 2 July 1769, the new church at the Ramen could be consecrated. The three-aisled hall church with galleries above the side aisles is built of brick, while sandstone was used for the entrance and the frame of the central window above the entrance. On both sides of the facade are brick block pilasters. From these points the walls recede in a concave manner, while the central section projects forward. In this central risalit is the natural stone entrance with rococo crowning in which the inscription: "how lovely / are / Your dwellings, LORD Zebaoth! Psalm 84:2". The wooden barrel vault is decorated internally with carved rocailles in two shades of blue, with rosettes inside. Restorations of the church took place successively in 1825, in 1850, in the years 1922-1923, 1962-1964 and finally in the period 1994-1995. In the 1922-1923, due to the decline in the number of parishioners, the church space on the east side was shortened and the freed-up space was used for a new consistory room and meeting room. The rectory dating from 1773 was also sold at that time, as was the sexton's house with a swan in the fanlight of the front door, which was built at the same time as the church.

St. Anthony's Church was built in 1671. Following the Reformation it became a Dutch Reformed Church. In the 1960s it was officially decommissioned.
