Architectural details like this enchant me. Architecture went through a period in the mid- to late-20th Century where this type of detail was often thought unnecessary. But we're starting to see the return of art for art's sake. This edifice is probably from the early 20th Century. Do you know where it is? Plain sight, busy corner, but who makes a habit of looking up?
The function of this meticulous brickwork is to look good. Is that function enough?
