Our morning promenade of discoveryin Luxembourg had been remarkable, and we were eager to resume the journey.
It was time for a stroll in the gorgeous Vallée de la Pétrusse. As we descended from the vantage viewpoints overlooking the valley, we passed Rue St. Ulric and then, Rue St. Quirin. The verdant valley gave us an entirely different perspective of the city. The walls of the ancient fortifications rose on either side.
