To get to know Vilnius, all you need is a 3-4 hour walk around the Old Town. Here is one of the sample routes around Vilnius, which will help you to cover maximum places worth seeing:
Let's start our Vilnius walking route at the foot of Castle Hill. Here, on Cathedral Square, is the country's main Catholic church, the Cathedral of Saints Stanislaus and Vladislav. Be sure to find a slab with the inscription Stebukla ("miracle" in Lithuanian) on the square in front of the church - if you make a wish standing on it, it will definitely come true!
The walking route around Vilnius continues in the Old Town - we walk from the Cathedral Square along the Castle Street (Piles). This is the oldest street in the city. Pay attention to the Orthodox church of Paraskeva Pyatnitsa - the sons of Prince Olgerd were baptized here.
The next point on the Vilnius tourist route is the incredibly beautiful Gothic St. Anne's Cathedral (Maironio g., 8), built of 33 kinds of bricks. According to urban myths, Napoleon himself was amazed by the beauty of this cathedral and even lamented that he could not take it to the capital of France.
After passing by the monument to A. Mickiewicz, we will head to another Orthodox temple - the Assumption Cathedral Prechistensky Cathedral of the XIV century. The minimum program is fulfilled - further we suggest you just wander along the narrow streets of Old Vilna!
