The great Rochester Castle towers over the city of Rochester, dominating the skyline together with its inseparable twin, the magnificent cathedral. These two buildings have resisted siege and destruction for over 900 years, and are all that remain of this war-battered keep.
On the day I took this picture, it was impossibly cloudy. I drove 2 hours for a sunset photo, only to arrive in the bleakest conditions. To my astonishment, the front passed over the castle grounds just as the sun sank toward the horizon, creating a beautiful rainbow that linked these two ancient buildings together.
