The Douro River is a major river in the Iberian Peninsula, flowing from its source in the Sierra de Urbión in northern Spain, through Portugal, and into the Atlantic Ocean at Porto. The Douro River Valley is also a breathtaking region in Portugal known for its stunning landscapes, world-renowned wine production, and rich cultural heritage. And it is spelled DOURO. Here is why....

The name "Douro" comes from the Latin word "Durius," which was used by the Romans to refer to the river. However, the river has had many names throughout history, including the Celtic "Dur," the Greek "Ourios," and the Arabic "Dawro." To many Portuguese, it is the D'Ouro - river of gold.

Sadly, the name gets spelled in many incorrect ways on lines from "Duoro" to "Duro" to "Doro." But, given its importance to the Portuguese, and the beauty of the UNESCO World Heritage Landscapes, it should be The Douro River. It has played an important role in the history of the Iberian Peninsula. It was used by the Celts and the Romans for transportation and trade, and it was a key trade route for the Portuguese during the Age of Exporation in the 15th and 16th centuries. The river valley is also famous for its vineyards, which produce the world-renowned Port wine and Douro DOC wines.

In addition to its cultural significance, the Douro River has had a significant impact on the natural environment of the region. The river and its tributaries support a diverse range of plant and animal species, and its valley is home to a number of rare and endangered species, such as the Iberian lynx and the imperial eagle.

Today, the Douro River is an important source of hydroelectric power, and it is a popular destination for tourists who come to enjoy its natural beauty, explore its historic towns and villages, and taste the world-class wines produced in the region.
