Shoot the details.

The entire story of the building cannot be told by a wide angle shot. You look at the whole building, and you tell a story which everyone else can understand if they stand in front of it.

You see, a postcard does the same. If you have actually walked into a historical building, see every detail of it, you "experienced" the place and its story, from the texture of the floor, the smell, the lighting, the artworks and all other subtle things. You really cannot say you get the same experience just by looking at the postcard.

So, shoot the very fine details of the building, and not just wide angle shots that includes everything. Shoot the floor to show it's texture, shoot the worn down decorations to show that it once was brand new. Shoot the chairs made of stone that so many people sat on, that the sharp edges became rounded and shinny.

Shoot the details, and you get a story that is multi-dimensional, that is rich, that is vivid, and leaves a strong impression. If you love that place, your photos will even show how attached you are to this special place.

Also, shoot new vs old. A brand new piano next to a century old piano that is about to break into pieces and get thrown away, can be an excellent shot to show the history of this place.
