the old barn wall
with every missing brick
a swallows nest
Just a 15 minute walk away from my house is a lane which leads down into a small valley. It's quite sparsely populated and you wouldn't know the bustle of a large market town was so close to hand.
About halfway down the lane is an old farm which would've been quite a proud building in its heyday. Attached to the farm is a barn. Walking down this lane during nesting season is quite something as the swallows twist and dip in and out of the barn wall.
