Finnart Oil Terminal

Two pipelines connect the terminal across Scotland to the Grangemouth Refinery on the Firth of Forth on the east coast, and extensive oil storage tanks have been built into the hillside on both sides of the main road.

[2] The road from Gare Loch rises over high ground before descending steeply to Loch Long, and at the foot of the hill the last owner of the croft on the site built a stone into the roadside wall with the inscription "This road was made from the Castle Rosneath to Tenne Clauch in the year 1777 by his Grace John Duke of Argyll.

[3] When World War II began, a jetty was constructed at the site together with pumps and tanks to supply fuel oil to naval vessels, by the same team of engineers who had covertly built an American base known as Rosneath naval base on the Gare Loch before the United States entered the war.

They built a direct 58 miles (93 km) long pipeline to deliver imported crude oil from the terminal to the Grangemouth refinery, and this was connected in 1954.

A deep-water jetty was constructed to accommodate the larger supertankers then coming into use, and the terminal also took over the Arddarroch estate, with the whole site leased from the Ministry of Defence.

[4][7] In September 2024, the owners Petroineos confirmed that the Grangemouth Refinery which connects to the terminal via two cross-country pipelines, would cease refining operations no later than June 2025.
