Plaza de Espana is a semi-circular brick edifice in the Renaissance or neo-Moorish style, with a tower at either end (tall enough to be visible around the city, these towers-north and south-are major landmarks). The majority of viceregal cities in Spanish America and the Philippines were built around a square "plaza de armas" where troops could be assembled, as the name indicates, and surrounded by the governor's palace and the main church. The Central Madrid Square, or "Plaza" in Spanish, is located in the heart of the city.
