The village was developed as a holiday destination in Victorian times on the site of a smaller and older farming settlement, and the first steamboat pier was built in 1851.
It was around this time that an American naval base in the nearby Holy Loch was established, providing some aid to the local economy, although being controversial.
The village's most striking landmark from its heyday as a seaside resort - the large Royal Hotel that overlooked the pier - was destroyed by fire in 1981 and the site has yet to be redeveloped.
Innellan's pier, which passenger steamers regularly called at whilst the area was booming, was extended in 1901 but finally closed in 1972 in response to reduced usage.
More recently, local resident Margaret Hubbard wrote a comprehensive collection of books about significant moments across the village's history.
