Exeter's Custom House anchors the quayside with the kind of practical grandeur that tells you the river once mattered commercially. Built for collecting duties on goods coming through the port, it now serves as a visitor centre and a compact introduction to the city's maritime and trading history.
The building is worth stopping for even if you only look from outside, with its formal frontage set against warehouses, cafes, water, and the busy leisure life of the quay. Go inside for local context before walking the river or hiring a bike. It makes the Quayside feel less like a pleasant afterthought and more like a working edge of the old city.
