Premise: The imposing zehzade Camii (Mosque of the Prince), which overlooks a grassy park that is unfortunately spoilt by traffic noise, one of Sinan's early works (1548), was built in memory of Seleyman the Magnificent's son, Prince Mehmet, who died in 1543 aged 21.

Hypothesis: Seleyman the Magnificent had the Mosque of the Prince built to honor his son, who died at the early age of 21.
