A monument rather than a conventional tower
Despite its familiar name, McCaig’s Tower is not a roofed tower that visitors climb through. The surviving structure is a monumental circular screen arranged in two tiers of pointed arches. Its open centre is landscaped as a garden, and its position gives broad views across Oban Bay.
Historic Environment Scotland describes the building as a unique combination of the plan of a Roman arena and Gothic arches. That combination, together with its commanding site, makes it one of the most recognisable buildings on Scotland’s west coast.
Why it is unfinished
The present ring was intended to be part of a much larger composition. Contemporary reporting described a tall central tower, public viewing platform, museum, art gallery and other buildings connected by arcades. John Stuart McCaig died in 1902, after the surviving outer work had already been left incomplete, and the wider scheme was never realised.
What it is today
McCaig’s Tower is a Category B listed building and a prominent public landmark. Visitors come for the architecture, the garden and the outlook towards Kerrera, Mull, Lismore and the mainland hills. There is no museum or visitor centre within the tower itself.
