Every night at midnight, an old clock tower in Prague made thirteen sounds instead of twelve.
Nobody knew why.
A young historian investigated.
He discovered that centuries earlier, a clockmaker had lost his daughter during a winter epidemic.
He changed the clock so it would ring an extra time every night.
The thirteenth sound represented one additional moment for remembering her.
The historian published the story.
Visitors began waiting for midnight.
When the thirteenth bell rang, everyone became silent.
The city seemed to pause.
The tradition continued.
Even today, the mysterious thirteenth sound reminds people that behind every old building, there may be a personal story that history forgot.
