Maps like these were typically highly detailed, with street names, landmarks, and other important features clearly labelled. They were often created in response to a specific need or demand, such as the need for accurate maps of trading cities like Limerick.
Today, copper-engraved maps like the one from the Eamon Norton collection are highly sought after by collectors, historians, and anyone with an interest in the history of Limerick and Ireland. They provide a valuable glimpse into the past and help us to better understand the evolution of the city over time.
