Restoration work on a Helensburgh church building with stained glass windows commemorating the inventor of TV and a former British prime minister is well under way.

The tower and belfry at Helensburgh Parish Church in Colquhoun Square is the focus of the work, which began just 12 days after final approval was received from the Heritage Lottery Fund in June.

The church's eye-catching stained-glass windows include memorials to John Logie Baird, who was born in Helensburgh in 1888, and Andrew Bonar Law, whose mother's family hailed from the town and who lived locally from 1891 to 1909.

The re-pointing of the stonework, rot repair and replacement of slates, along with work on the B-listed building's gutters, downpipes and drains, has received funding awards of £94,000 from both the HLF and Historic Environment Scotland, while the church itself is contributing a further £100,000.

Inside the church, damaged and uneven stones in the vestibule floor will be replaced and some electrical works will be taking place, as well as works on doors.

Several of the church's stained-glass windows have also been removed for restoration; the whole project is due to be completed by September 30.

The church's congregation now plans to research all the people commemorated on the building's stained-glass windows and to publish the information online and in booklet and audio-visual form.

A major rebuild of the church halls was completed earlier this year, and is proving of great benefit not just to the congregation, but also to the wider community.

The church's minister, the Rev David T. Young, said: “The restoration work currently taking place, together with the new church halls, will ensure that members of the Church of Scotland in Helensburgh will have an appropriate place for worship for many years to come.

“There will also be improved heritage information, including audio-visual material and via the church’s website, new open days and tours, with the involvement of schoolchildren and volunteer guides.

“The generosity of the Heritage Lottery Fund and of Historic Environment Scotland is making a major contribution towards this."

The present church building was opened in 1853, and was originally home to the town's Free Church congregation, though the site has been used for worship since 1825.

The Helensburgh Parish Church name dates from 2015 when the congregation – then known as St Andrew's Kirk - united with that of Park Church in Charlotte Street.
