The Museu Mineralógico Da Escola De Minas (Mineralogy Museum) can be of special interest to visitors. It belongs to the UFOP's School of Mining, which opened its doors on 12 October 1876. The museum is located at the Praça Tiradentes (No. 20), in the town's historical center, and contains a rich assortment of minerals on display, including precious and semi-precious gemstones and large crystals. Security is tight, however (for example, no cameras are allowed), due to the incalculable value of the gemstones and ores on display.
