"The function of a building can influence its appearance, and many types of buildings have distinctive features that make them easy to recognize, such as a church tower or a store window. Often these features have a practical as well as decorative purpose: a church tower, for instance, may hold the bells used to call people to worship. Familiarity with these key features will help you recognize different sorts of buildings, but elements from one type of building can also be used as decorative items on an entirely different sort of building, often to try and link one type of construction with another." - How to Read Buildings

"Understanding buildings is like detective work: you need to look for clues that will lead you to recognize the building. These clues might be windows that have been altered, changes in materials, or fragments of older structures left behind during alteration work, or they might be smaller, subtle things such as minor details or curious irregularities that make you wonder why the building is like that. Every structure is different, and like a good detective you need to approach each one with an open mind. However, there are some common clues that you can look out for." - How To Read Buildings
