The most prominent feature of the structure is the castle-like turret on the corner. Mackintosh built it to include over 8000 gallons of water, an early fire extinguisher system to protect goods inside should the building have ever caught fire.

Almost a century after it was built in 1895 and after two decades of lying abandoned, it was renovated and launched as The Lighthouse. Due to its Mackintosh heritage, it has a section devoted to the architect and artist’s life and work, as well as the history of the building itself. From here, you can also ascend the spiral staircase that winds its way up the tower. The walk is worth it, as when you reach the top you will be greeted with panoramic views of Glasgow's rooftops.

As well as other exhibits, The Lighthouse has positioned itself as a central hub for creativity in the city. As well as lectures and workshops in a variety of fields, and the recent addition of a Digital Design Gallery, the centre holds a bi-monthly design market, allowing craft makers to sell their works to the general public.
