Slateford Aqueduct: Visiting Hours, Tickets, and Comprehensive Guide to Edinburgh’s Historic Landmark

Date: 04/07/2025

Introduction: The Slateford Aqueduct and Its Significance

Positioned in the southwest suburbs of Edinburgh, the Slateford Aqueduct is a monument to Scotland’s industrial ingenuity and the transformative age of canal engineering. Completed between 1819 and 1822, this structure was envisioned and executed under the expertise of Hugh Baird and with the counsel of Thomas Telford—two of the United Kingdom’s most renowned civil engineers. Designed to carry the Union Canal over the Water of Leith and Slateford Road, the aqueduct played a pivotal role in the transportation of coal, building materials, and agricultural produce, fueling the capital’s expansion during the Industrial Revolution (The Four Sisters Boatel; Canmore; Historic Environment Scotland).

Today, the Slateford Aqueduct is celebrated not only for its technical achievements but also for its integration into Edinburgh’s green corridors, including the Union Canal towpath and Water of Leith Walkway. This guide offers a detailed overview of the aqueduct’s history, architectural features, practical visitor information, and ideas for exploring nearby attractions—making it an essential resource for anyone keen to uncover the layers of Edinburgh’s industrial and natural heritage.

1. History and Engineering

Origins and Construction

The Slateford Aqueduct was conceived as part of the Union Canal project, a 31-mile (50 km) “contour canal” connecting Edinburgh to the Forth and Clyde Canal at Falkirk. Its design, which meticulously followed a single elevation to minimize the need for locks, demanded innovative solutions to traverse Edinburgh’s undulating terrain (Scottish Places). The aqueduct, completed in 1822, was the first major canal crossing west of Edinburgh and set the precedent for subsequent structures such as the Almond and Avon Aqueducts.

Engineering Highlights

Designers: Thomas Telford (advisor) and Hugh Baird (engineer)
Construction: 1819–1822
Length: 183 meters (600 feet)
Number of Arches: 8, each with a 15.2-meter (50 feet) span
Materials: Locally quarried stone for arches and piers; cast-iron trough for the canal channel
Towpath: Located on the northern side only
Structural Innovations: The use of a cast-iron trough was pioneering, enabling watertightness, reducing the load on masonry, and reflecting advancements seen in earlier Telford projects (Canmore).

The aqueduct was vital for the efficient movement of coal and goods into Edinburgh during the 19th century. The Union Canal and its crossings, including Slateford, were instrumental in supporting local industries and urban growth. The aqueduct’s continued presence highlights Edinburgh’s evolution from an industrial hub to a city that values both heritage and sustainability (The Four Sisters Boatel).
