Rome
The eternal city is a breathtaking legacy of two of the world's greatest empires: the ancient Romans and the Catholic church. It's monuments, history, architecture, culture and style are second to none and form a fantastic backdrop to a wedding of any size.
For ceremonies there are literally hundreds of Catholic churches together with the places of worship of most other denominations. There are also several Town Halls for civil non religious ceremonies. Alternatively have a blessing ceremony in your reception venue.
