Here are a sample of the model lighthouses made on our recent visit to Souter Lighthouse. The children created a switch which completes an electrical circuit and lights up the bulb so they can switch the light on and off. They decorated their model lighthouses to their own designs. At Souter, we learnt that lights were switched on and off for particular amounts of time and this became a code for seamen so they could identify the lighthouse from as far away as twenty miles. Souter lighthouse always shone a red light so it could be easily identified and was the first light to be lit using electricity in Great Britain.
