Doorway to Heaven

Sorry, but the first thought I have is to wonder how long it will take for someone to put text into that opening in the sky and turn it into a cartoon-like thought-baloon. This is a stretch for me to connect with the challenge description, but I guess it could fit if you envision heaven as a hidden city of gold up there somewhere.

Definitely hidden, with a deep blue sky (whether from using a filter on camera or adjusting in post processing), and a relaxing looking place - although one that looks far away from any city.

Merry Christmas - Union Station, Washington, DC

I enjoy the geometric composition with the curved stairs and arched ceiling setting off the darker lines of walkways, handrails, and escalators. Those casual eating areas are not featured in magazines, but make up the hidden heart of a city.

The jumble of traffic and pedestrians contribute to hiding the Royal Society building. They help this meet the challenge, but I have a feeling of irritation at not being able to have an unobstructed view up the narrow opening -- perhaps the point you are making.

I like the range of colors as well as the combination of shapes. Looks like the street slopes down to the left, which gives an intersting semi-off-balance efect to the image. Nice find.

Quiet city parks often serve as hiding places for sculpture. I wish we could see more of the Gandhi figure.

Hidden

Comment:
The isolated building on a narrow sunlit ridge feels all the more hidden because of the multiple layers of shades of blue extending out as far as the eye can see. I imagne the lack of obvious connection to "city" will make many vote on the lower side of the scale.

Closed down railroad - Access forbidden

Comment:
Well composed with the curved tracks dividing the dark trees and brush from the brighter slope on the other side. Is this hidden in some part of a city?

Hidden along the back of these buildings, the fire escapes make an interesting pattern of repeating metal lines. You captured the feeling of height well enough to make me feel a little dizzy.

Good choice of unnatural processing to go with the unnatural decorations -- an interesting bit of residential pop art.
