Above Madrid’s grand boulevards, seven jets carve the Spanish flag across the autumn sky. Every October 12, Spain celebrates its Fiesta Nacional de España — the Día de la Hispanidad — marking the 1492 anniversary of first contact between Europe and the Americas. The highlight is the military parade down the Paseo de la Castellana, presided over by King Felipe VI, where thousands line the streets waving flags as the Patrulla Águila acrobatic team paints the sky red and gold. For teachers drawn to language, history and living culture, there’s no richer classroom than the one waiting when you Teach English in Spain.
