This place is steeped in history: the city of Groningen arose, strategically located, on the northernmost part of the Hondsrug, an elevated glacial ridge of sand and clay, so that the inhabitants were relatively protected from high water and invaders. Alongside this Hondsrug the Drentse Aa river flowed towards the sea, which enabled a bustling trade. Here, at the Hoge der A and the Lage der A, the city’s first harbor arose where the resourceful Groningers constructed a low and high quay for continuous loading and unloading during ebb and flood. Until well into the 19th century, the influence of the sea was perceptible in Groningen. Today the canals and associated quays create a rich public space for locals and visitors.. The historic warehouses and ships provide a picturesque spectacle.
