Mission Concepciòn de la Purisima, a church dedicated to the Immaculate Conception of the Blessed Virgin Mary, is also a working parish. At the time the church was built the mission fathers were into the alignment of buildings, beyond the basic rule that churches face the east. (This is based both on the theological teaching that Jesus is the Light of the world and an ancient tradition that He will return from that direction.) This church has a beautiful alignment of windows that results in a sunbeam landing directly on certain images once a year. The volunteer that was there when we visited had made a cell phone video of the most famous sunbeam which he showed to us. It was beautiful!
The sunbeam illuminates this painting, lingering on the image as it transits, in an amazing way. There is also at least one other alignment in this church, which illuminates another holy image which is to the left. The church is cruciform, that is, shaped like a cross, and in the second illumination the sunbeam crosses the church directly above the crossing of the arms of the cross.
The parish has a banner of the current jubilee year. I think that Mission Concepciòn is one of the (many) regional churches that make a Jubilee pilgrimage accessible even to people who can't visit Rome. The stylistic contrast between the old stone buildings and the modernistic (Tyvek?) sign is interesting.
This mission is in the middle of a neighborhood of the city, not too far from a golf course and many businesses, and using a map app is recommended to find it.
