Poço Silveira is a small, rural spring well in Castelões—good for intimate landscape and architectural details: stonework textures, damp shadows, and quiet countryside backgrounds. Visit on clear mornings for soft light and low harsh contrast; weekdays keep the area calm. No entry fees are typically expected, but access is on foot/nearby paths—respect private land and keep quiet.
