I can't help but notice every picture that captivates my interest, ultimately is a +ppigeon's work. I guess what I'm trying to say is that I like your style. Thank You for sharing your talent.
It's the St-Nicholas church. It was finished in 1735. The writer Franz Kafka was born in a house that stood close to this church.
For location, look here (point 3 on the map)
What a wonderful image you've captured!!! The lighting makes the picture majestic. Especially since it's green, a color that can symbolize growth and blossoming.
This picture brings to my mind some of images of "magic of the Disneyland", with its gradient of light in a background, and mysterious colours of the detail. Yes, this place calls - come here, experience the life as it used to be then, when no rat race was known, when we all were more for each other than for ourselves. There is another place in Praha - the famous church called Loretta, quite similar in its spirit to this one. Each night at 6pm the famous bells of Loretta play - and call for prayer. It is an extraordinary experience - strongly advise not to miss while in Prague.
