Its important role in the lives of those of Acadiana is, in a unique way, summed up by the song Allons a Lafayette, the first Cajun song to be recorded, which makes mention of going to Lafayette to be married. This site says a bit more on that subject: http://www.louisianafolklife.org/LT/Articles_Essays/cajun_wed.html
Here is a recording of the song by Lee Benoit:

In any event, Lafayette, Louisiana is today the seat of the Catholic Diocese of Lafayette, whose neo-Romanesque or Romanesque-revival Cathedral, the Cathedral of St. John the Evangelist, was completed in 1916AD. It is certainly a striking example of its kind! It was constructed, as the sign above notes, on ground donated in 1821AD.

Just next to the Cathedral is a truly magnificent speciman of Live Oak (Quercus virginiana), known as the St. John Cathedral Oak. This tree, thought to be nearly 500 years old, is a splendid example of what the great oaks of the South can grow to be. It is 9 feet 2 inches in diameter, 126 feet high, and 134 feet across!
