History
Vigo has a long history. The urban area of Vigo was built over both a hill-fort (Castro) and a Roman settlement. In fact, it is generally accepted that the name Vigo comes from the latin word Vicus. During Middle Ages the small village of Vigo was part of the territory of neighbouring towns, mainly Tui, and suffered several Viking attacks.
However, the number of inhabitants was so small that, historically, Vigo is not considered to be a real village until around the 15th century, when the earliest records began.
In the 16th and 17th centuries, the city was attacked several times. In 1585 and 1589 Francis Drake raided the city and temporally occupied it, leaving many buildings burnt. Several decades later a Turkish fleet tried to attack the city. As a result the walls of the city were built in 1656 during the reign of Felipe IV. They are still partially preserved.
During this time, and in spite of the attacks, the city of Vigo developed its earliest commerce, and was given several privileges from the kings of Spain.
In 1702 the Battle of Rande occurred, and in 1719, because a Spanish fleet which departed from Vigo attempted to invade Scotland, the city was temporarily seized by an English fleet.
In the Sixties, Vigo suffered a very important 'industrial revolution'.(see more in Wikipedia)
