Triangulation Points

I like collecting things. Triangulation points are a favourite along with benchmarks that can be found along a walk or near to one.

There is something very satisfying about reaching a trig pillar, partly I guess because they invariably involve a walk up hill and a reward of sweeping views, weather permitting. There are 84 pillars within the Peak District National Park boundary and many more triangulation points and thousands more benchmarks.

Some are not shown on maps with the traditional blue triangle, the one at Hey Edge for instance, built but never used for triangulation, but was used for levelling, so does it not qualify for the blue triangle.

Some triangulation points are not even pillars. One of my walks takes in the Hunting Tower on the Chatsworth Estate, the triangulation point being the flagstaff. Another is the centre of the spire of All Saints Church in Bakewell.

With the advent of GPS the triangulation pillar network became largely redundant, but a few still do have a purpose. The pillar at Harland South, levelling bracket number 2998 is part of the Global Positioning Network and as such is protected by Ordnance Survey. A plate informs the visitor that any damage should be reported to the phone number.

Triangulation points always come in a minimum of three so a favoured walk of mine takes in the Hunting Tower at Chatsworth, the pillar at Birchen Edge along with the Three Ships and the pillar at Harland South, passing Hobs House, one of the first ancient monuments to have legal protection in the UK, on the way. Two pillars, one part of the Global Positioning System and one flagstaff on a hunting tower. Not bad for a day out.

Bakewell Church Spire SK 2156 6848 SK39/INT46

Not all triangulation points have  a triangulation pillar or a benchmark plate. The latest walk started at the Grade 1 listed All Saints Church in Bakewell, the triangulation point being the church spire.  The church is interesting for its architecture and stained glass windows, the local benefactor and landowner features large in the proceedings. From the church I headed south east for the next trig.

Noton Barn SK 2166 6616 S4183 208m

Noton Barn is at the top of a small rise overlooking Bakewell and Haddon. Tracks and pasture land make the walk a pleasant stroll especially on a sunny day. The triangulation pillar itself is situated in the corner of a field, unadorned and in perfect order. Heading back across the fields to the next trig there are wonderful views of the medieval Haddon Hall estate, which is reached following a short descent to the A6 road.

Calton Pastures SK 2377 6817 S 4152 289m

The route rises from the road, through the Haddon Estate and on to the Chatsworth Estate. Climbing up the hill and through the trees, a rail tunnel, now sealed is passed. The tunnel was used to hide the rail line from Rowsley to Bakewell from the sensitivities of the Duke of Rutland who owned Haddon Hall. The Monsal Trail starts at Bakewell and continues on to Topley Pike east of Buxton, it is a fine walk or cycle especially now that the tunnels have been opened and floodlight during daylight. Calton Pastures sits between Bakewell and Chatsworth House, nestled against a wall, with views across to Edensor and Chatsworth Park.  From the trig it is a simple and pleasant descent back in to Bakewell.  The route does cross a golf course, and a large bell has to be rung to warn golfers of your presence, this is very satisfying, especially if one can time the ringing in the golfers mid stroke, such pleasures should be taken whenever they can be had.
