Groenlo

Groenlo is a city in the Netherlands, located in the province of Gelderland. It is part of the municipality of Oost Gelre, in the eastern part of the country near the border with Germany. The town lies in the historic Achterhoek region and is known for its compact center and visible remnants of medieval fortifications and gates.

The settlement dates to the Middle Ages and grew around a fortress that gave the town its historic name Grolle, later Groenlo. In the Eighty Years' War, Groenlo was the site of a famous siege in 1627, when Dutch forces captured the town from Spanish rule after a protracted bombardment. The siege is a key episode in the conflict and influenced subsequent military engineering in the area. Over the centuries the fortifications were partly rebuilt and later diminished as the town expanded.

The town is historically linked to brewing; the Grolsch beer brand derives its name from Groenlo, reflecting the region's brewing heritage. Today Groenlo maintains a historic town center with museums and heritage sites that highlight its past, while serving as a local center for commerce and community life within Oost Gelre.
