John Strain, circa 1866. 12-segmental arch viaduct, with sturdy tapered piers, set across mountain side. Bull-faced, coursed masonry. Occupies dramatic location on W side of Glen Ogle.

Statement of Special Interest

Situated in the Northern half of Glen Ogle, running parallel to Creag Na h-Iolaire. The first meeting of the Committee of the Callander and Oban Line was held in 1864 and royal assent was given for its construction in 1865. In 1866 the contract for the section of line running through Glen Ogle was given to the contractor John McKay of Ann Street, Edinburgh. Various drawings, dated 1866, are held in the National Archives of Scotland (NAS) for bridges on this line. Amongst these papers is a design for a viaduct (RHP120173), but it is for one of 20 arches and therefore not the final design for the present viaduct. The plans are signed by the contractor and the engineer, but unfortunately the name of the latter is illegible. Gordon Biddle states that John Strain was the engineer. Confusingly, the Callander and Oban Railway is shown on the First Edition OS map, which was surveyed in 1862 and published in 1867. It seems likely that the map must have been updated shortly before it was published. The line was opened in 1870.



Plans for various bridges on Callander and Oban Line at NAS, ref RHP120170-5. Appears on 1st Edition OS map, 1862 (see Notes), G Biddle, 'Britain's Historic Railway Buildings' (2003), p662.

About Listed Buildings

Historic Environment Scotland is responsible for designating sites and places at the national level. These designations are Scheduled monuments, Listed buildings, Inventory of gardens and designed landscapes and Inventory of historic battlefields.

We make recommendations to the Scottish Government about historic marine protected areas, and the Scottish Ministers decide whether to designate.

Listing is the process that identifies, designates and provides statutory protection for buildings of special architectural or historic interest as set out in the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.

We list buildings which are found to be of special architectural or historic interest using the selection guidance published in Designation Policy and Selection Guidance (2019)

Listed building records provide an indication of the special architectural or historic interest of the listed building which has been identified by its statutory address. The description and additional information provided are supplementary and have no legal weight.

These records are not definitive historical accounts or a complete description of the building(s). If part of a building is not described it does not mean it is not listed. The format of the listed building record has changed over time. Earlier records may be brief and some information will not have been recorded.

The legal part of the listing is the address/name of site which is known as the statutory address. Other than the name or address of a listed building, further details are provided for information purposes only. Historic Environment Scotland does not accept any liability for any loss or damage suffered as a consequence of inaccuracies in the information provided. Addresses and building names may have changed since the date of listing. Even if a number or name is missing from a listing address it will still be listed. Listing covers both the exterior and the interior and any object or structure fixed to the building. Listing also applies to buildings or structures not physically attached but which are part of the curtilage (or land) of the listed building as long as they were erected before 1 July 1948.

While Historic Environment Scotland is responsible for designating listed buildings, the planning authority is responsible for determining what is covered by the listing, including what is listed through curtilage. However, for listed buildings designated or for listings amended from 1 October 2015, legal exclusions to the listing may apply.

If part of a building is not listed, it will say that it is excluded in the statutory address and in the statement of special interest in the listed building record. The statement will use the word 'excluding' and quote the relevant section of the 1997 Act. Some earlier listed building records may use the word 'excluding', but if the Act is not quoted, the record has not been revised to reflect subsequent legislation.

Listed building consent is required for changes to a listed building which affect its character as a building of special architectural or historic interest. The relevant planning authority is the point of contact for applications for listed building consent.
