Any others that you are aware of?

Thank you, griego catolico, for the links. It would be nice if I showed you the the Vladimir Icon of the Most Holy Theotokos (we celebrate the Feast today), but there is no webcam in the church I find it is a good idea to have it.
But you can see for example the interior of the Сhurch of St. Peter and Paul in Moscow

Or just a beautiful view of the Church in 3D http://3dpanorama.ru/underground/church-vt/tour.html

Saint Isaak Cathedral in St. Petrsburg

The Church of the Savior on spilled blood

And some more beautiful views from St. Petersburg



and Moscow


Interesting to see beautiful places all over the world!
