The plans
Surviving drawings record proposals for a stone-and-lime wall, a granite tower and later additions. John Stuart McCaig devised the scheme himself.

An unfinished monument · A complete Oban icon
A vast ring of granite arches rises above Oban Bay: part family memorial, part employment project and one of Scotland’s most memorable architectural follies.

The story
McCaig’s Tower was conceived by John Stuart McCaig, an Oban banker, writer and amateur architect whose ambitions reached far beyond a simple viewing point.
The scheme was reported in 1895, while 1897 is commonly given as the start of major construction on Battery Hill. McCaig wanted to create a permanent monument to his family while providing work for local stonemasons during the winter. He planned a great circular structure inspired by ancient arenas, but filled it with the pointed arches of Gothic architecture.
The outer screen was only the beginning. A central tower was intended to rise within it, accompanied by a museum, an art gallery and statues of McCaig and members of his family. When McCaig died in 1902, construction ended. The unrealised centre left the sky as the tower’s roof and transformed an unfinished Victorian project into Oban’s defining silhouette.
A short chronology
Surviving drawings record proposals for a stone-and-lime wall, a granite tower and later additions. John Stuart McCaig devised the scheme himself.
Construction starts on Battery Hill, providing skilled local stonemasons with valuable winter employment.
McCaig dies before the central tower, museum, gallery and family statues can be realised. Only the monumental outer ring is complete.
The structure is formally listed at Category B for its architectural and historic interest.
The unfinished shell encloses a public garden and frames a celebrated outlook across Oban Bay.
Architecture
The monument is a circular granite screen built directly onto the rock of Battery Hill. Its arena-like plan is divided into two tiers of tall, pointed openings: 44 below and 50 above.
Rough-faced local granite gives the exterior its powerful presence. Inside, irregular masonry and open arches throw moving shafts of light across the garden. The raised eastern entrance is round-arched, with pointed windows and a commemorative plaque above it.
Plan your visit
McCaig’s Tower is on Battery Hill, a short but steep climb from central Oban. Set aside at least 45 minutes for the walk, garden and views — longer if the weather is kind.
On foot
Routes from central Oban involve steep streets and steps. Allow time and wear footwear suited to wet or uneven ground.
By road
Drivers can approach from Duncraggan Road. Parking close to the entrance is limited and the surrounding residential roads are narrow.
At the tower
There is no ticket office or admission charge. Weather, maintenance or local restrictions can occasionally affect access.
Find the tower
Check the forecast before setting out. West coast conditions can change quickly.
The view west
The island of Kerrera shelters Oban Bay; beyond it lies Mull. Ferries, fishing boats and yachts cross the view below, while Lismore and the mainland mountains extend the panorama northwards.
Good to know
‘Folly’ is an informal nickname for an ornamental structure with little obvious practical purpose. It also reflects the fact that McCaig’s much larger plan was never completed.
The circular plan recalls a Roman arena, but the pointed openings are Gothic. Historic Environment Scotland describes the result as a unique combination of a Roman-arena plan and Gothic arches.
Plans included a central tower, a museum and art gallery, and statues commemorating McCaig and members of his family. Only the outer screen was built.
The outlook takes in Oban town and harbour, Oban Bay, Kerrera and, in clear conditions, Lismore, Mull and the hills beyond the Firth of Lorn.
