The original purpose of the temple was simply a landscape feature or ‘folly’, designed to be seen from the mansion house and by visitors arriving at Castle Semple. It also served as a summer house with panoramic views. The design of the building probably comes from James Gibbs ‘Book of Architecture’, published in 1728, a sort of architect’s scrapbook of ideas. Gibbs described his designs as ‘summer houses in the form of temples of an octagonal form. The Follie originally had a roof and glazed windows but these were damaged in a fire. It also had trees planted beside it.

Loch Thom is a reservoir which since 1827 has provided a water supply to the town of Greenock in Inverclyde, Scotland. It is named after the civil engineer Robert Thom who designed the scheme which created the reservoir and delivered water via a long aqueduct known as The Cut. Today, as well as providing a water supply, the loch is used for sport fishing and forms part of the Clyde Muirshiel Regional Park with several attractive walks and a centre at Cornalees Bridge providing nature study facilities.

The Prophet's Grave is the burial site for the 17th-century preacher, the Reverend William Smith, and is located in the Brisbane Glen near Largs The Reverend William Smith died aged 28 from the plague in 1647. Smith only arrived to minister in the town three years before his death, having worked as a schoolmaster in nearby Irvine. He never married and records show that he died with only his books and his clothes. Such was his dedication that he continued to minister to his parishioners even after he had contracted the plague. Local legend recounts that he became known as the 'Prophet' because upon his deathbed he prophesied that Largs would be forever protected from plague or pestilence as long as the holly trees growing at his grave were prevented from touching. Older records indicate that the holly trees were located at the 'head' and 'foot' of the grave, however today two trees are located either side of the 'head' and three at the 'foot'. Relatives and others maintained the grave site and the result, intended or otherwise, of Smith's prophecy is that the site has been maintained and his name has never been forgotten. The grave site now consists of a recumbent stone standing on stone blocks near the Middleton Burn that runs down to the Noddsdale Water in the vicinity of the old Noddsdale corn and flour mill.

Barr Castle is a 15th-century keep which was altered in the 16th century (and probably later, too). The gables of the castle have collapsed, apart from the chimney stack which juts up into the sky. Not much survives of the former courtyard of the castle. The main hall was on the first floor, reached by a turnpike stair, which continued to the rooms on the upper floors. It is clearly visible from the A760 road going south from the village to Kilbirnie. It was built by the Glen family but passed in the late 16th century to the Hamiltons of Ferguslie. A door lintel has a date of 1680 and the initials L.H./I.C. The family abandoned it in the 18th century in favour of a new house. The family, variously known as Sempill, Sempil, Sempel and Semple, had probably owned estates in the area from as early as the 13th century. Robert Semple, Steward of the barony of Renfrew during the reign of Alexander II, was recorded as living in Elliston Castle, whose ruins lie near Howwood. The Semples of Elliston fought for Robert the Bruce, and steadily grew in power to become the Steward's hereditary Baillies of Renfrewshire. They were appointed Hereditary Sheriffs of Renfrewshire and Hereditary Baillies of Paisley. They were later designated as Lords Semple. Their extensive land holdings, Castle Semple, constituted some areas of Lochwinnoch and its hinterland. At some point, probably in the 15th century, the family built a tower keep at the east end of the north shore of the Loch.
