Courtyard Entrance, The Glen

The Bridge Over Kill Burn, also known as the Entrance Bridge, was designed by David Bryce in 1858 and 1874 for Sir Charles Tennant. This two-span Scots Baronial bridge features pointed arches and corbelled semi-octagonal pedestrian refuges, leading to a castellated archway with bartizans and trefoil detailed walls that enclose a courtyard. The bridge is constructed with droved and polished yellow sandstone ashlar dressings and coursed whinstone walls, including the parapet and soffits.

On the northwest and southeast elevations, there are three semi-octagonal pedestrian refuges that sit atop triangular buttress piers and cutwaters. A pointed arch spans the river between the first and second refuges, featuring moulded dressed ashlar voussoirs and a stepped hood-mould that supports a slightly projecting parapet wall. A hybrid pointed/segmental arch spans the road between the second and third refuges, using similar style and materials. The plain whinstone wing walls have advanced plain parapets carried on a string course to the sides, with moulded coping on all parapets. The plan is reversed on the southeast elevation, which includes gun-loop details at the far left, indicating an interior room.

Inside the southwest pier, there is a segmental-arch vaulted room made from random rubble, with evidence of past whitewashing suggesting it may have been used as a cool store for estate produce. This room has a stone and earth floor and is lit by long gun-loops in the southeast wall. The other bridge piers appear solid.

The northeast elevation, which serves as the entrance to the courtyard, features a moulded segmental-arched entrance with stepped hood moulding that forms a full-length string course. An inset panel inscribed with "SALVE" rises into a battlemented parapet that terminates in bartizans. High plain walls with trefoil and gun-loop details adjoin the kitchen and offices on the left and the stables on the right, all topped with moulded coping.

The southwest elevation of the courtyard has a hood-moulded, segmental-arched entrance at the center, flanked by heavy stepped buttresses and a battlemented parapet with an inset panel inscribed "VALE." The plain walls with trefoil and gun-loop details adjoin the stables on the left and the kitchen/office range on the right, with moulded coping surmounting all.
