Lochleven Castle is reached by passenger ferry. The castle dates to the early 14th century. Lochleven was the location of a confrontation between Mary Queen of Scots and John Knox in 1563. She was held prisoner here from June 1567 until her escape in May 1568.
The north curtain wall separates the inner and outer courtyards with a single entrance providing access between the two.
The two cannon date to the period of the Napoleonic Wars and were probably brought to the castle much later to enhance its appearance.
The castle is now in the care of Historic Scotland and has retained some of the old Ministry signs.
