Apart form a few strained glances out the oval window of a passenger jet, most Dubliners have never seen their city from the air.
Denis Horgan's Dublin: The View from Above takes to the skies to give us a new perspective on Ireland's capital. With over 240 jaw-dropping photos, the book offers a comprehensive bird's eye view of Dublin's historic buildings, parks and monuments.
"Seen from the edge of an open aircraft door, the city below looks breathtaking," says Horgan.
"Flying in both helicopter and fixed-wing aircraft, usually with a door removed to get clearer shots and unobstructed camera angles, I managed to capture all the iconic Dublin landmarks, from Cristchurch to Dublin Castle, in a new light, many from striking angles."
The aerial photographer also notes a few surprises - such as the number of swimming pools in the Docklands, and the existence of a rooftop hockey pitch.
Horgan's photos reveal the massive physical changes our historic city has undergone.
As broadcaster Pat Kenny says in the book's introduction, "Modern buildings sit sometimes uncomfortably beside the old imperial heart of the city, but somehow this reassures us that this generation is making its mark and we are not a city set in aspic."
Dublin: The View from Above, published by Collin's Press, is available in book stores nationwide for €24.99.
