As a former researcher, I should remember to fact-check before publishing. The basilica here in Quito was built in the 1890s, not 1492. That was when the Christianization of Latin America began.
I blame my still-improving Spanish reading skills for the error... but still, 400 years wrong is a rather obvious blunder, and the numbers in Spanish are the same - so that's a pretty feeble excuse! :)
