Tyrnavos (Greek: Τύρναβος, from the Slavic "Tirnovo", a "thorny place") is a municipality in the Larissa regional unit, of the Thessaly region of Greece. It is the second largest town of the Larissa regional unit, after Larissa. The town is near the mountains and the Thessalian Plain. The river Titarisios, a tributary of the Pineios, flows through the town. Tyrnavos is bypassed by the GR-3 (Larissa - Kozani - Niki) and has an old road connecting the town to Elassona. It will be linked with a superhighway numbered 3 (A3) with an unscheduled opening date. Tyrnavos is located south-southwest of Thessaloniki and Katerini, northwest of Larissa, east-northeast of Trikala and south-southeast of Elassona and Kozani.
Tyrnavos was built by the Slavs as a pastoral settlement with huts in the 7th or 8th century AD. In 1423 the Turkish general Turahan Bey conquered the area of Thessaly. Turahan founded Tyrnavos, gathering the local inhabitants and settling them in the new town, which he adorned with several buildings and which he granted extensive privileges. In 1770 there were 16 churches and 6 mosques in the town. Tirnavos was liberated from Ottoman rule on September 1, 1881 and by decision of the Berlin Congress, Greece annexed it. The Turkish bath is the only Muslim building to have been saved as well as some other preservable buildings of the town.
Carnival & the "bourani" 
The city holds a famous annual carnival, which has its roots in antiquity. It is at least 100 years old. The first written records about its celebration date from 1898. In the early 20th century, the carnival of Tirnavos has been the target of bitter criticism and successive attacks by the governments of that time that regarded it as an offence against the moral standards of people. However, the prohibition of the carnival didn’t intimidate the inhabitants of Tirnavos that celebrated it even secretly.
After the war, disguised people are incorporated into the carnival chariots. However, the dictatorship prohibited it once more and its celebration was interrupted until 1980 when the custom was revised. In recent years, the carnival of Tirnavos is renowned as the biggest and best carnival in Central Greece. The carnival is celebrated during about a month, but the festivities culminate on the last Sunday of carnival with the big Parade of chariots, with the participation of thousands people.
The custom of “Burani” takes place on the day of (Clean Monday), the first days of Lent. This customs have made Tirnavos famous. Shrove Monday is a day of merry moral freedom or laxity of morals during which the rules of decent behavior are temporarily violated. The use of sexual and love symbols are combined with the traditional folk manifestations. Strictly speaking, the “bourani” is a folk fare but in essence, it is a phallus festival that symbolizes the reproduction and fertility. First, the inhabitants of the town go to the country church of Prophet Elijah in a free wide area, in the north of the town. Each group spread a table with various dishes on the ground and a big flagon of wine or “ouzo” or “tsipouro” with water.
At the same time, they lit a fire on which they prepared the “Bourani”, a spinach soup. After the “Bourani” had been served to the “initiates”, people started dancing, singing, joking and teasing each other using obscene language. Everyone who passes by must stop and stir the soup with a long wooden ladle of a particular shape, take a sip of soup straight from the ladle and then drink a shot of tsipouro from a ceramic phallic-shaped tumbler. Next to the cauldron, there is rocking throne in the shape of a phallus, which attracts flocks of laughing festivalgoers.
A lot of men that participated in this ritual held phalluses as scepters in their hands. The phalluses were made of wood or clay or even of bread and constituted the most important ceremonial symbol. In the late seventies, women started taking an active part in the entire ritual especially after the creation of the “Bourani Society” in 1979.
This pagan fertility festival in honour of the god Dionysus marks the beginning of the Greek Orthodox fasting period before Easter. Due to the intense pagan roots of the festival and its irreverence, the Greek Orthodox Church does not approve of the event.
