The Belgian Promenade forms part of a scenic walk beside the Menai Strait from the Menai Bridge to Church Island. It was built during the First World War by refugees from Mechelen in Belgium. The residents of Porthaethwy provided them with food and shelter and, in gratitude, the refugees built the promenade. It was completed in 1916. After storms and high tides caused erosion in the 1960s, the promenade was rebuilt by the local council. As well as providing a pleasant walk, the Belgian promenade is an excellent place for bird watching.
