Next to the synagogue is the eighteenth-century wrought-iron gate from the Ascoli house, believed to be the ancient gateway to the ghetto.

Through the gate, a pedestrian path and a staircase named after Rabbi Isaac Samuele Reggio lead to Via Brass below, where the Corno River, now buried, once flowed. Here, on the Jewish New Year (Rosh HaShanah), Jews symbolically freed themselves of their sins by throwing stones into the flowing water, which carried them away. The small garden behind the gate is dedicated to the memory of Bruno Farber, the youngest Gorizia native deportee, killed in Auschwitz at the age of 3 months and 19 days. Inside, an environmental art trail for children has been created, featuring an installation by Emanuele Luzzati evoking the Jewish holiday of Purim.
