Here is another moody, stormy sky that really seemed to make all the colours glow. Despite the dry spring, the trees of Shipley Glen and the fields on the flanks of Hope Hill are looking lush and green. The clear lighting picked out the peculiar little glazed watchtower on the roof of 47 Titus Street, Saltaire. No-one seems quite sure why it's there. It may have been simply a decorative touch, being more or less central in the village, but in the 1870s the house was the home of Salts Mill's security chief and so the tower may actually have been used as a watchtower.
