Walking north to Tui on the camino from Valenca do Minho which was the old frontier you pass through a spendid a 17thc fortress designed by Vauban and then cross the river Minho on the 19th c International bridge designed by Eiffel. The view to Tui as the lights come on at dusk is splendid! Within the fortress the camino passes through the garden of the pousada/hotel Sao Teotonio. Stop at their outdoor bar to sip a coffee or more, relax and admire that panoramic view.
Bom caminho and Buen caminho!
