Architecture, archaeology and continuing use

The rectangular basin opens through its sheltered side, while a broad harbour arm projects into the bay to protect the entrance. Rubble fabric is reinforced by concrete and a raised seaward wall.

Its story

Built and financed in 1825–28, the harbour was almost destroyed in January 1839. After its channel was cleared, major works in 1884 rebuilt the structure in concrete at a recorded cost of £12,000.

Why it is included

Category B listing captures both nineteenth-century commercial ambition and a major engineering response to coastal damage.

What to notice

  • The broad arm shielding the entrance.
  • Contrasts between rubble and concrete work.
  • The raised wall facing open water.

Reading the surroundings

Remain on authorised routes, avoid closed or working sections and keep back from exposed edges in poor weather.

Timeline

  1. 1825–1828 A larger basin expanded Portsoy’s capacity under Seafield patronage.

What we know — and what remains uncertain

The designation does not state the responsible designers for either principal phase.
