Photochain Challenge: 135th Edition Start WINDOW and SPLITTING

Hello, feel-good community greetings🙏. Thanks, Hive account@davidesimoncini for the last contest. according to my understanding splitting means cracking, or started separating. then here is my entry belonging to the last winner's keywords window and splitting. This photo I took yesterday while coming back from work suddenly saw this small old building opposite my workplace. having this splitting in beam of wall beside the window.

In all photos, we can clearly see besides the window the splitting on the beam of the wall. My keyword is a chain.

little more close up.
