Santa Cecilia in Trastevere
Santa Cecilia in Trastevere was a refuge for me back in the day. The nuns sang Gregorian chant for the Mass each day (still do) and it was a foretaste of heaven, locus refrigerii lucis et pacis. Here is a photo of the inside:
And here is the statue of St Cecilia by Stefano Maderno. He depicted her incorrupt body as he saw it when the tomb was opened in 1599. Notice the cut on the neck, and the hands showing one finger and three fingers as a profession of faith in the Holy Trinity. Just too beautiful for words.
