One of the highlights of the Main stop was the magnificant cathedral
we saw. Filled with enormous rooms, chapels and elaborately sculpted stone
carvings, it was a center of Mainz both spiritually and culturally from
900 A.D. until the late 17th century.

St. Martin's Catholic Cathedral. This picture does NOT do
it justice. The only cathedral I've seen to match this one is
Westminster Abbey in London. This one is magnificent!

The "Dom" or archbishop who wielded incredible religious
and secular power in medieval times. This fellow was responsible
for building this cathedral and is buried in a crypt under the church.
(Note: That is sunshine glaring on the camera lens and NOT divine intervention)
My biggest interest in Mainz was in seeing the Gutenberg Museum,
named for their famous son Johannes Gutenberg. I believe that the
World Wide Web is the most fundamental change in human communication since
Gutenberg invented the printing press. I was not disappointed. See why here.
