This Gaudi–designed church is a tour fix­ture for almost every vis­i­tor to Barcelona. But the man whose name inspired the word “gaudy” was­n’t going to con­cep­tu­al­ize some low-key neigh­bor­hood church. The Sagra­da Famil­ia (“Holy Fam­i­ly”) is one of the world’s most debat­ed works of archi­tec­ture; some peo­ple love the dra­mat­ic Gothic–inspired spires and columns, while oth­ers con­sid­er them an eye­sore. One thing is clear: This mon­u­men­tal struc­ture, due to be com­plet­ed on the cen­te­nary of Gaudi’s death in 2026, can­not be ignored.
