known also as Monaco Cathedral where many of the Grimaldis
were buried, including Grace Kelly and more recently, Rainier III.
The Romanesque-Byzantine cathedral was consecrated in 1875,
and is on the site of the first parish church in Monaco built
in 1252 and dedicated to St. Nicholas. Of note are the retable
(circa 1500) to the right of the transept, the Great Altar
and the Episcopal throne in white Carrara marble.
