Be collected at your accommodation in Zagreb and drive for approximately three hours to Pula. This is the biggest city and the center of the Istrian peninsula. The city was founded by an ancient tribe in the 10th century B.C. and it was well known by Greek travelers and sailors so is mentioned in many Greek myths. In the 1st century, the Romans made the city strong and today the vivid remains of this era can be explored. Pula Arena is one of the best-preserved amphitheaters in the world and will take you back in time as you imagine gladiators battles. Other examples of Roman architecture to discover are the Temple of Augustus and the gates to the city including the Arch of the Sergii and the gate of Hercules.  Continue your journey for 45 minutes to Rovinj. This city was also founded by the Istrian tribes. It was built on a small island close to the mainland and in the 18th was connected to it. It was ruled for five centuries by Venice so both the Italian and Croatian languages are spoken in the city. During this period of occupation, walls were built around the city and the remains are standing still today. Rovinj is a real gem and adored because with every step you take you are compelled to take another photograph. Travel another 45 minutes to Porec. The Old Town is almost 2000 years old and is most famous for the Euphrasian Basilica, from 1997. It is on the UNESCO world heritage list and one of the most popular tourist destinations in Istria. Notice the roman influence and architecture in the city as you walk through the main streets, still preserved in their original form.
