Three views of High Tor and the houses in the valley below, the earliest of which dates from 1892 (plus an enlargement of a section of one of them).

The top photograph was taken by Calitta M. Tinti (née Whittaker) of Matlock Bath. Just visible on the top of High Tor is the wooden Refreshment Room that was burned down around 1997 or 1998^[1]. In the valley below is the house where Calitta's son, Remo, lived and operated his coal business from for many years (one of the houses bottom, right). He provided coal for most of Matlock Bath.

Detail of above, showing the houses that were demolished in 1966.

Further along the road is a building next to the pavement with coach houses / stables underneath it built in 1830 by Thomas Robinson; there are two pairs of semi detached gabled houses, set back slightly to the left, which were built in the 1890s. Behind them is the rock face of a small former quarry. In January 1966 these houses hit the headlines when the owners had a luck escape after part of the hillside collapsed behind the properties about lunch time, demolishing one of the buildings. "Jagged cracks appeared in the cliff face and the rock wall behind the houses began to creep forward with steadily increasing momentum." The residents watched it all from across the road as "the 80 ft high 'creeeping cliff' slipped forward, engulfing their homes^[2]." The hillside came down in what can only be described as a huge avalanche. It must have been an extremely traumatic experience. The remaining pair of houses also had to be demolished, as did the properties above the coach houses.
See Tor Hill House, Dale Road, Matlock Bath, 1915, formerly Tor House, for more information.

You need to look hard at the photo above but you can just about see the bridge across the river that leads to the colour works, which is roughly opposite.

The second image pre-dates Mrs. Tinti's picture by some years and was probably taken before 1900 and maybe as early as 1892. The Edwardian houses mentioned above had yet to be built. However, the colour works bridge and even the rooftops of the colour works buildings can be seen, although they are not easy to spot.

The final full sized picture is one of a series of images of Matlock Bath and Matlock Dale scenes, published in snapshot format rather than as a post card. The photograph provides a good view of the houses opposite High Tor, so you can see Riversdale and Glena Cottage, for example, with Heath Bank and Craven Villa below. It is also the clearest view of the colour works and its bridge.

When it was advertised for sale in 1876 and 1882 Riversdale was described as a "Bijou Residence" but as it had "dining and drawing rooms, a library, a large entrance hall, staircases and landings, and seven bed rooms, bath room, and w.c. together with useful domestic offices, plus stabling for three horses" so it was hardly small but it was definitely an elegant building^[2].

The seven houses higher up the hillside behind Riversdale were, from the left, Grove Mount and then Riversdale Cottages. In 1877 they were occupied by Messrs Ward, Cotes, Wilks, Short and Cooper, one property was used as a laundry to Riversdale and the other was untenanted. In 1882 "Grove Mount" with gardens was in the occupation of Rev. Cotter and the cottages were the homes of Messrs Hadfield, Hope, Robinson and Miss Whitehead^[3].

Detail of image 4, showing the houses opposite High Tor in 1892. Note the publisher's number scratched on the image - and written backwards.

See who was living in some of the properties in the 1901 census (see pp.16 and 17). It is less easy to tell who the householders were in the 1891 census.
There is another coloured image of the Switzerland View in the "Just Images" Matlock Dale section of this website.
