I'm struck by the significance. The walls allowed the Byzantine Empire to outlive the Roman Empire by ten centuries. Their undoing marked the end of medieval times (the collapse of the Western Roman Empire marked the start).
Another fun fact, it took about 800 years, or four Islamic caliphates before the event happened in the Ottoman Caliphate era, after Rashidun, Umayyad and Abbasid Caliphates [2].
And another fun fact, one of the prophet trusted sahabat namely Abu Ayyub al-Ansari was involved in the very first campaign of the First Arab Siege of Constantinople during the Rashidun Caliphate [3]. He died during the event in his old age of over 90 and become the patron saint for Istanbul, Turkey. His tomb/mosque was the official inauguration place for almost all of the Ottoman Caliphs [4]. He also famously hosted Muhammad in his house for several months during the migration or Hijrah to Yathrib (modern Madinah), where Hijrah date is the start of Islamic calender.
