Rome has a rich history pertinent to western civilization. There are three different aspects of roaming in Rome, namely, architecture, history, and religion (Catholic - Christians). I was profoundly interested in history and to some extent, in architecture, and that influenced my itinerary.
A day in Venice Compared to Prague, Rome, Vienna, and Split, Venice is a tourist trap. The city is made up of a collection of 100+ islands. Bridges connect most of them, and you can walk throughout the city. All the public transport is using water buses called Vaporetto. A single trip costs 8 Euros. If you are planning to use Vaporetto, buy a 24-hour pass worth 20 Euro which covers unlimited trips on Vaporetto.
