The Structural Forms of Polish Lighthouse Architecture

The lighthouses standing along the Polish Baltic coast represent a distinct chapter in the wider history of European maritime construction. Built predominantly between the 1820s and the early twentieth century, these towers reflect the engineering conventions and material choices of their respective periods, modified by local conditions including Baltic weather patterns, coastal topography, and the availability of construction materials.

Construction Materials and Masonry Traditions

The majority of Polish Baltic lighthouses erected in the nineteenth century used fired brick as the primary structural material. The region had well-established brick manufacturing traditions, particularly in Pomerania, and brick offered adequate compressive strength for tower structures while being locally procurable.

The Świnoujście lighthouse, completed in 1857 and standing at approximately 68 metres from ground to lantern room, is built from yellow brick and represents one of the more ambitious applications of this material in Baltic lighthouse construction. The tower's cross-sectional dimensions decrease with height in a pattern consistent with structural load calculations of the period.

Iron was used selectively. The replacement tower at Rozewie, installed in 1875, is constructed from prefabricated cast-iron sections assembled on site — a construction method common in the second half of the nineteenth century when prefabricated iron lighthouse components were manufactured and exported across Europe. The Rozewie tower's iron structure required regular repainting to prevent corrosion, a maintenance requirement documented in Urząd Morski records.

Construction Note

Brick towers on the Baltic coast typically used lime mortar rather than Portland cement in their original construction. Restoration work carried out since the mid-twentieth century has in some cases introduced Portland cement patching, which conservators have noted creates differential expansion issues over time.

Tower Geometries

Polish Baltic lighthouses fall into a small number of geometric categories. The most common form is the circular cylinder — a tower of consistent or slightly tapering circular cross-section. Niechorze and Kołobrzeg both use this form. The circular plan distributes wind loads evenly around the structure, a practical advantage in a coastal environment where storm winds can approach from varying directions.

Octagonal towers appear at several sites, including the original Rozewie structure (now no longer standing). The octagonal plan was considered easier to construct than a true cylinder since it allowed straight-run brickwork on each face, though it introduced slight stress concentrations at the corners.

Lantern Rooms and Optical Equipment

The lantern room — the glazed enclosure at the top of the tower housing the optical apparatus — followed standardised designs that allowed lens equipment to be installed and replaced without modifying the surrounding structure. Most Polish lighthouses used lantern room designs with polygonal or circular cast-iron frames and large pane glazing.

Fresnel lens systems were the standard optical equipment installed from the mid-nineteenth century onward. These lenses concentrate light into a narrow beam through a series of concentric prism rings, enabling the light to be visible at distances far exceeding what flat glass optics could achieve. The original Fresnel lens installations at several Polish lighthouses have been removed and replaced with modern LED lamp units, though some lens assemblies have been preserved in situ as technical heritage objects.

The Fresnel lens at Niechorze was a third-order dioptric system manufactured in France, typical of the equipment imported by the then-German administration of Pomerania in the latter nineteenth century.

Keeper's Dwellings and Ancillary Structures

Most Polish lighthouse complexes include or originally included keeper's dwellings positioned adjacent to or connected with the tower base. These residential buildings generally followed the domestic architectural conventions of their period and region — in West Pomerania, this meant single or two-storey structures with pitched roofs and brick construction consistent with local vernacular building practice.

The functional requirements of a lighthouse station in the pre-automation era determined the programme of ancillary structures: residential accommodation for keepers and their families, a fog signal house (where fog horns or explosive signals were maintained), oil stores for lamp fuel, and in some cases a small workshop. Automation of Polish Baltic lighthouses, carried out progressively during the second half of the twentieth century, made resident keepers redundant and many associated buildings were subsequently repurposed or transferred to other uses.

Wartime Damage and Post-War Reconstruction

Several lighthouse structures along the Polish Baltic coast sustained damage during the Second World War. Kołobrzeg, for example, was heavily affected during the fighting of 1945 and required substantial post-war reconstruction. In some cases, the post-war rebuilt towers deviate from the pre-war architectural record, introducing concrete elements or modified geometries that distinguish them from their predecessors.

The distinction between original pre-war fabric and post-war reconstruction is relevant to heritage assessments, since conservation approaches may differ depending on which elements represent the historically significant original construction.
