From the Ark to a permanent station

Marine work at Millport began before this building. John Murray brought the floating laboratory Ark to the bay in 1885, joining the investigations of local naturalist David Robertson. A permanent station gave that activity a more substantial base. Later work by Sheina Marshall and Andrew Picken Orr helped establish the importance of Calanus in marine food systems.

A building enlarged for science

Peter Macgregor Chalmers designed the western wing in 1896–97. An addition followed in 1904, and J. B. Wilson, Son & Honeyman supplied the eastern wing in 1939. The resulting U-shaped building uses red and cream rubble, slate roofs and prominent gables. Large semicircular windows on the seaward fronts are particularly distinctive.

Research, teaching and collections

The statutory history connects the expansions with aquarium, classroom, museum and library provision. The fabric therefore records changes in scientific practice as well as increasing accommodation. The Robertson Building is listed at Category C. The listing’s interior observations date from 2014; they are not a statement of present access or condition.
