The Unfinished Colosseum Watching Over Scotland’s Most Beautiful Seaside Town

Standing on Oban’s harbour, something stops you. High on the hill above the town, a ring of stone arches catches the light. For a split second, you wonder if you’ve somehow stepped into Rome.

A Victorian Banker With an Impossible Dream

That structure on the hill is McCaig’s Tower. It was built by John Stuart McCaig — a local banker, philosopher, and proud son of Oban — who began construction in 1897.

McCaig had spent his life in Argyll. He had done well. And as he aged, he wanted to leave something permanent behind — something that would outlast him and reflect his love for his town and his family.

He modelled his vision on the Roman Colosseum. He wanted the same sweeping arches, the same sense of ancient grandeur. He wanted it to sit on Battery Hill, two hundred feet above the bay, where it could be seen from every corner of Oban.

Generosity Built in Granite

McCaig had a practical reason for building too. Oban’s stonemasons faced hard winters with little work. By commissioning a major project, he gave them steady employment through the lean months.

The granite came from local quarries. The men cut and hauled it up the hillside, arch by arch, through the winters of the late 1890s. What McCaig built was practical generosity wrapped in an impossible dream.

He paid for the construction entirely from his own pocket. He treated the monument and the employment it created as equally important — an act of love for the town that had made him prosperous.

The Vision That Was Never Fully Realised

McCaig’s original plans were ambitious. Inside the outer walls, he intended a central tower, a museum, and bronze statues commemorating his family members. The arches were to be the frame. The real vision lay within.

He completed the outer ring of walls. The arches rose to their full height. But the interior — the tower, the statues, the museum — was never begun. McCaig died in 1902, before a single stone of the inner structure had been laid.

A Garden Where Statues Never Stood

After his death, the tower passed to his sister, Margaret. She had no funds to continue. Ownership eventually passed to the local council.

The grand interior plans were quietly set aside. Rather than leave the space hollow, the council created a garden inside the arched walls. Today, there is grass and flowers where McCaig imagined bronze statues and museum halls.

It is both more and less than he intended. Somehow, that makes it more moving.

What You See from Battery Hill

The walk from the harbour to McCaig’s Tower takes about ten minutes on foot. A path winds up through the town’s streets. Locals walk their dogs here in the mornings. Couples sit in the garden at dusk. Visitors stand quietly against the arches and stare out to sea.

The view is extraordinary. Oban Bay spreads below you. Ferry boats cross toward the tiny islands that sit just off the coast. The dark bulk of Mull fills the horizon. On clear days, Jura and the hills of Islay rise faintly to the south.

It is one of those Scottish views that resets something in you.

Why Oban Is Worth Slowing Down For

Oban is often called the Gateway to the Isles. Ferries leave from its harbour to Mull, Colonsay, Tiree, and beyond. If you are planning a multi-stop trip through Scotland, Oban is a natural place to pause for a day or two.

The town itself rewards a slower visit. The seafood is outstanding — fresh-landed prawns and scallops right on the harbour. The bay is beautiful at every hour. And the climb to McCaig’s Tower costs nothing, takes ten minutes, and stays with you far longer than that.

McCaig wanted to build something that would last. What he left behind — a ring of arches on a hilltop garden above the sea — has lasted remarkably well. If you are wondering which Scottish town to visit first, Oban is a strong answer.

Whatever he imagined inside those walls, what remains outside them is something genuinely singular. A ring of stone watching over one of Scotland’s loveliest seaside towns — not quite finished, not quite Roman, not quite like anything else on earth.
