Reconnect with your spiritual side and offer up your own prayer at Santuario de la Peregrina. Sit in quiet reflection outside for a while or ask if you're able to join the next service.
When you've finished exploring this Sahagun house of prayer, why not make your way to San Tirso Church, San Pedro de las Dueñas Monastery, and Iglesia de San Lorenzo? They're not very far from Santuario de la Peregrina and also a favorite with travelers.
