In 1869, as the small town of Callander was beginning to reap the benefit from the influx of trade brought by the newly established railway, William Glen opened a small drapery store to serve the rising population. As the prosperity of the town continued to grow, William Glen outgrew his original shop, moving to larger premises to extend his range. The business continued to develop and after several further moves, William Glen & Son eventually settled at 82-86 Main Street where it remained in its high profile location for many years as one of Callander’s largest shops.
