Codrii Vlăsiei was the forest that once covered parts of southern Romania, including the territory of today's Bucharest and the surrounding Ilfov County.
The thick forests were used by Romanians as a retreat during the age of migrations because they were not easy to cross on horseback. In fact, the name of the forest means "the Forests of Wallachia". Codrii means "forests" in the Romanian language, while Vlăsiei is the genitive form of Vlăsia, the Slavic denomination for Wallachia.
The thick forest was also useful in the Middle Ages, being used by several voivods to defeat other armies. In 1456, Vlad Ţepeş defeated his rival Vladislav Dan at Târgșor at the edge of Codrii Vlăsiei. This was also the place where Vlad defeated the Ottoman army that came to depose him. It is also thought that Vlad was assassinated there following a plot of the boyars. The forests were later a hideout for highwaymen, haiducs and other outlaws.
Between 1692 and 1700, a paved road which linked the centre of Bucharest to the Mogoşoaia Palace of Constantin Brâncoveanu was built through the forest. Named Podul Mogoșoaiei, it was made of oak wood. Most roads in the Balkans at that time became muddy in the spring and autumn, and the wood prevented this. Consequently, the road was one of the most important construction works of the area and a source of pride to Bucharesters. In 1842 the road was paved with cobblestone. It was later upgraded to asphalt. The road was renamed "Calea Victoriei" after the Romanian victory in the Independence War of 1877-78.
