Over at the New Liturgical Movement, there is a set of photos of St Marien in Berlin. The first shows the Church in the late 19th century. The second shows the Church after a 1960s aggiornamento which involved whitewash but thankfully did not destroy the Church too radically. The third shows the recent restoration after the Church came into private hands. The notes by Shawn Tribe interpreting this as an allegory of the reform of the reform are well worth reading.
