Vratsa's motto is "A city like the Balkan – ancient and young".

The name comes from the Vratsata Pass nearby, and derives from the Slavic word vrata ("gate") + the Slavic diminutive placename suffix -itsa, "little gate", used to translate the Latin name Valve ("double door"). The name of the town during Ottoman era was recorded as Ivraca.

The Ottoman census records of the early 1550s indicate that İvraca was in a continuous development. According to this, there were 82 Muslim households, corresponding to approximately 400 people, and a mosque, later known as "Eski Camii", with also a population of 31 unmarried males. The Christians living in 12 neighborhoods, on the other hand, reached a population of approximately 1840 with 354 households and 172 unmarried males. At this time the ratio of the Muslim population to the general population increased to 18%. In addition, it is mentioned in the defter that the Muslim and non-Muslim population in the city and some residents of the 2 neighbouring villages were working in the mines and therefore these workers and their families were exempted from the avarız property tax. In 1580, Muslims made up 30% of the total population. At that time, the city had 3 Muslim neighborhoods (mahalle-i Câmi-i Atik, Mahalle-i Câmi-i Cedid, Mustafa Çavuş Mescidi mhalle). There were a total of 258 households in these neighbourhoods. The Christian population also increased, reaching a total of 583 households in 12 neighborhoods named after their priests. Apart from these, there were seven Coptic mining households whose statuses were recognized in 1550. The number of monasteries, which was 4 up to this date, increased to 8.

1831 Ottoman population statistics show that 74% of the Christians were non-taxpayers in the kaza of İvraca and 83% of the Christians were recorded as middle-class.

Vratsa is an ancient city found by ancient Thracians. Vratsa was called Valve ("door of a fortress") by the Romans due to a narrow passage where the main gate of the city fortress was located. Nowadays, this passage is the symbol of Vratsa, and is shown on the town's Coat of arms.

After the fall of Rome, Vratsa became part of the Eastern Roman Empire (Byzantium).

At the end of the 6th century AD, Vratsa was populated by the South Slavic tribes. Even if they came from Pannonia and Dacia on the north, the town remained under Byzantine rule.

In the 7th century, the Bulgars and the Slavs found the First Bulgarian Empire and the Slavic Vratsa became part of it. The city grew into important strategic location because of its proximity to the South State border. Vratsa became famous for its goldsmiths and silversmiths production and trade, high-quality earthenware and military significance.

In the 8th century, the Bulgarian army captured Sofia, which led to the decreasing of Vratsa's importance because of the better strategic position of Sofia, its more developed economy and larger size. But Vratsa was again key for the resistance against the Byzantine, Serbian and Magyar invasions in the Middle Ages.

On 1 May 1966 in the village of Sgorigrad, a Mir-Plakanista mine tailings dam collapsed, causing a flood of mud and debris that killed 488 people. It remains one of the biggest disasters in Vratsa since the 30 September 1923 fire and the Anglo-American bombing of 23 January 1944.
