The picturesque Penmaenpool Bridge is one of only a few wooden structures of its kind in Britain. A famous landmark the rickety wooden toll bridge spans the Mawddach Estuary. Replacing the ferry, the wooden bridge was built in 1879 by the Penmaenpool Bridge Company. Although the Dolgellau to Barmouth railway is no longer in use, indeed the rail track bed now forms the route of the Mawddach Trail, the signal box has been retained to make an attractive feature, which is now leased to the RSPB as an information centre.
