The Cregneash Shipping Direction Finding Station was a mid-20th century installation located on Cronk-ny-Array hill to the east of Cregneash. Two masts are shown on historical OS 1:10560 scale mapping published in 1958 to the south and east of the technical buildings, together with the annotation, 'Automatic Wireless Transmitting Direction-finding Station (Shipping)'. The masts have now been removed and the buildings converted for residential use.

Modern corn drying kiln. A corn-drying kiln was discovered during ploughing on Croit e Caley farm, Colby in 1968. An emergency excavation revealed a substantial though much ruined structure. Clear traces of burning, with large quantities of charcoal, were found, together with a well-preserved 'drying-pot' built of cobbles, and a millstone. Paving and a possible flue were also identified. No dating evidence was found, but its excavator AM Cubbon and BRS Megaw (1969) consider a 17th-18th century date is likely.
