with known id's / lots of 'monument' in file desc)
86 edits for Cpiro

Several more in top 30 uploaded buildings, which could be related but also might not be,
e.g.
98 edits for Maharajsaran
http://tinyurl.com/9qfqwav (not categorized as monument, and
perhaps not meant for WLM)
85 edits for MartinSilk
http://tinyurl.com/9rjuamx (might be cemetery rather than WLM,
although quite a few buildings)
88 for Andries Van den abeele
http://tinyurl.com/95f7hck (streets rather than buildings)
