crenel

“The crenels are all flat now. It’s slippy and feels dangerous when I walk on it.”

Drifts climbed the walls and filled the crenels along the battlements, white blankets covered every roof, tents sagged beneath the weight.

On the inside of the rampart and in the wide crenel between two upthrust merlons.

The heads were mounted between the crenels, along the top of the wall, impaled on iron spikes so they faced out over the city.

Over it there is sprung a high-arched, rough stone bridge, with crenelled walls, quite as artistic in its way as may be found in pictures of ancient English brook-crossings.
