These are the twin spires of the
Basilica del Voto Nacional, in Quito.
Not very old (begun in 1887, inaugurated
101 years later), it is the largest neo-Gothic
basilica in the Americas. Also maybe the highest,
since it sits on a high point of the city (which is
already more than 9,000 feet above sea level).
