The complex is located on the summit of a slight knoll about ten metres from the shoreline of the Holy Loch on the Cowal Peninsula in Argyll, Scotland.

[3] Most of St Munn's Parish Church as it appears today dates from the 19th century, although the old, ruined tower located to the west of the present building (now a scheduled monument) belongs to a much older foundation.

[5] At that time, Kilmun was closely linked with Paisley Abbey, and St Munn was adopted as the patron saint of Clan Campbell.

The now partly ruined tower to the west of Kilmun Parish Church was the residence for these six clergymen and a place of refuge for the local population during dangerous times.

[9] Conservation of the mausoleum and construction of the visitor centre with a series of interpretation panels[10] began in the spring of 2013,[9] and the refurbished site was opened to the public in April 2015.

Volunteers now offer regular guided tours of both church and mausoleum on Thursdays, Fridays and Saturdays, from the beginning of April through to the end of October.

[4] At the head of the T-shaped building is a small, modern square bell tower with corner finials and a pierced stone parapet, over an advanced, gabled central bay.

The church contains a number of stained glass windows, many by Stephen Adam, including life of Christ scenes and a portrait of George Miller of Invereck as St Matthew.

[4] In 1898–99, the architect Peter McGregor Chalmers re-arranged the interior of St Munn's, forming an open choir in the place of the closed vestry on the southern wall.

[15] The current building thus replaces an earlier chapel in the collegiate church and records indicate that Chiefs of the Clan Campbell have been buried or commemorated here since the 15th century[14] – a total of twenty generations over 500 years.

[5] While the installation of the large cast iron dome helped to improve lighting within the mausoleum, it was never properly sealed to the supporting walls and water began to enter the building.

St Munn's congregation were concerned and, assuming that the mausoleum was the property of the Duke of Argyll's Estates, requested that the problem be addressed.

You can now visit the beautifully restored mausoleum, church and visitor centre from Thurs - Saturday, 10am - 4pm, between the beginning of April and the end of October.

The mausoleum is on a square-shaped floor plan with the pointed-arched entrance on the northern elevation, flanked by two blind-traceried lancets and applied pilasters.

The decision to put such a heavy object on the extant mausoleum walls seems to have been controversial at the time, although the weight proved to have little detrimental effect.

[9] The interior of the Argyll Mausoleum consists of two platforms on the side walls with niches for coffins,[4] which are covered with inscribed sandstone slabs.

[7] In the centre aisle of the mausoleum, between the tombs lining both side walls, stood a life-sized sculpture of an angel lifting Christ from the Cross.

It was made by the Marquess of Lorne's wife, Princess Louise (Queen Victoria's fourth daughter), who was a skilled artist and had married the future 9th Duke of Argyll in 1871 and now resides inside a glass showcase in the visitor centre.

While the burials of clan Chiefs' wives were not recorded in the same way, the majority of them will have been buried beside their husbands and other unrecorded close family members will also lie at Kilmun.

The churchyard at Kilmun Parish Church contains a number of interesting memorials, including later medieval tapered slabs and several high quality post-medieval headstones (mainly from the 17th and 18th century) as well as table-tombs carved with trade tools and the Douglas Mausoleum (see below).

[4] As part of the programme of community events organised by the Argyll Mausoleum Ltd, several areas of the graveyard have now been surveyed and the inscriptions been recorded.

The octagonal structure was built in 1888 from red sandstone and features rock-cut ashlar walls, a studded timber door with a carved armorial panel above it and a stone-slabbed roof.

The mausoleum contains the remains of General Sir John Douglas of Glenfinart, GCB (1817–1888), a military commander during the Indian Mutiny.

To the north of the church is the final resting place of Elizabeth Blackwell, the first qualified female physician in the United States.
