Where am I?

In a bar on Broadway Market in London there is a brilliant artwork which consists of loads and loads of pictures of red front doors in (I assume) London. Like a book shelf, a front door is a bit of statement - are you traditional (red, racing green, navy blue with brass door knob), slick and modern (duck egg blue or other pastel colour and (at the time of writing) frosted stencils for numbers), or do you not care what others think of you (same colour and style as when you moved in 8 years ago). In central Berlin, practically everyone lives in apartments behind a communal door so you don't have the ability to project something about yourself to the people passing at street level (window boxes I can come onto in time). But that has not prevented me from finding doorways and street signs interesting!

In Berlin street numbers are either illuminated cubes attached to the wall or hanging down from the porch ceiling, or more old-fashioned tin plaques which (if you're lucky) point in the direction that the numbers go in down the street. Sometimes numbers are odd on one side and even on the other, and other times they go up one side of the street and come down the other. Helpfully, signs on street corners tell you what numbers are along the next block and sometimes an explanation about the name of the street. So Sonntagstraße is not so-called because it is a nice place to hang out on Sundays, but after Johann Sonntag, who was a late 18th century landowner and leased out the fields round today's Boxhagener Straße to farming families. And Ede-und-Unku Weg is named after a 1931 book which was included in those burned as part of the 1933 book burning, as part of the city's remembrance of victims of the Nazi era.
