Interior of the Church of St. Francis, Porto, Portugal

When it comes to church interiors no church can perhaps rival the “Baroqueness” of the Church of Saint Francis in Porto, Portugal, decorated with more than 650 pounds of gold dust.
The sharp contrast between its sober Gothic exterior and its glittering internal naves makes the Church of Saint Francis one of the most intriguing examples of Catholic architecture in the country.
Each of the three internal naves, including the roofs, pillars and window frames, was decorated with elaborate engravings and coated with gold.
Napoleonic troops stole some of the Church of St. Francis's golden engravings during the 19th century.
