Friday's unexpected downpour that witnessed incessant thunder and lightning not only caught the city unawares, but also served as a wake-up call for its heritage structures. The Army & Navy building at Kala Ghoda was struck by a streak of lightning that led to the collapse of the crown of a gable (triangular portion between intersecting roof pitches) from its façade on the topmost portion of the building. However, thanks to the original lightning arrestor installed on its pediment, it did not impact the main structure to a large extent except for the surrounding stone that broke away. Luckily, no one was injured. Yesterday, a hanging loose stone was removed for safety, revealing the sturdy pipe fixing detail of the copper thong that ensured no further damage to the affected portion.
