You can't miss Lancing College chapel. It looms large on the horizon from every direction - a neo-Gothic edifice that stands 50m tall thanks to some of the most ambitious architecture design of the mid-1800s. Its gloomy silhouette acted like a magnet, and we drove to it on a whim, not knowing if it even accepted visitors. Turns out, it positively welcomes them. Perched in the middle of a congregation of buildings that make up the private school - established in 1848 - it still hosts services for the pupils each Sunday, but outsiders are welcomed in every day to view the extraordinary arches, the gigantic organ, and the largest rose window - that's the beautiful stained glass number in the picture - in England. We were shown around by a kind volunteer - a friend of the school, whose children had been boarders here long ago. Fascinating, awe-inspiring - and free!
