Parish of Viseu municipality.

The minerals of this locality are in veins in granitic pegmatite, with massive quartz, 30 cm orthoclase crystals (many of them, when extracted from the quartz, present a perfect form), tourmaline (schorl), perfect complex crystals (some of them over 20 cm), beryl (15 cm crystals) and rare topaz (5 cm maximum).
