On the Giara's southeastern flank, the town of Gesturi is dominated by the 30m-high belltower of the Chiesa di Santa Teresa d'Avila. The faithful flock to this 17th-century parish church to celebrate Gesturi's greatest son, Fra Nicola 'Silenzio' (1882–1958), a Franciscan friar revered for his religious devotion, wisdom and simplicity of life.
