Carolinensiel church, Brick church in Carolinensiel, Germany.

Carolinensiel Church is a rectangular brick hall church with a hipped saddle roof, built in 1776 and standing on the dike. Four large basket-arched windows pierce each long side, and the only portal, with a dark green door, is on the west side. Leafless climbing vines cover much of the walls, and a cross stands at the left end of the roof ridge.

The first settlers on the new dike, built in 1730, still attended services in Funnix or Werdum. Permission to build a church came only in 1770, and the brick hall church was consecrated on 20 October 1776. The free-standing brick tower followed in 1793, kept deliberately low because of the strong storms.

The church is also called Deichkirche (dike church) and Schifferkirche (sailors' church). Three votive ship models hang inside: the brig Venus (1776) left of the altar, the frigate Alje Mehrings (1921) right of it, and the barque Marie Emilie (1985) on the north wall. The red box pews contrast with the white interior.

The church is easy to find as it sits centrally in the village and is visible from the main streets. Keep in mind this is an active place of worship, so checking opening times ahead of your visit is wise.

The church is one of only two churches worldwide built on a dike, and its low brick tower of 1793 was kept short because of the heavy storms. The tower is topped by a swan, a Lutheran symbol, and holds two bells tuned fis and a; the small one was recast in 2001.
