A fragment of Havana's early ramparts commemorates the spot where eight medical students were unjustly executed for independence activism by the Spanish governors in 1871. At night the monument is beautifully illuminated, the work of the electrical engineer Félix de la Noval. You'll see amber light representing rifle fire; it can't, however, extinguish the white light (against the wall), which symbolizes the ideals of independence.
Paseo de Martí (Prado) y Av. del Puerto (Calle Desamparado/San Pedro), Havana, Cuba
