Military remains
Coast Defence Battery No. 3
Also at Suurupi stand the remains of Coastal Battery No. 3, part of the chain of batteries on Naissaar, Aegna and Suurupi that was meant to close the Gulf of Finland and guard the waters off Paldiski. Its four 6-inch Canet guns sat on concrete bases, with reinforced-concrete shelters for crews and ammunition beside them and a separate command post on the left flank; its field of fire covered the fairway between Naissaar and the mainland. A cobbled road still leads to the position, and two searchlights, one near Ilmandu, lit the water at night.

Samuti Suurupis on rannakaitsepatarei nr 3 jäänused. Patarei kuulus Naissaare, Aegna ja Suurupi patareide ahelasse, mis pidi Soome lahe sulgema ja kaitsma Paldiski-esist veeala. Neli 6-tollist Canet' kahurit asusid betoonalustel, nende kõrval raudbetoonist meeskonna- ja laskemoonavarjendid ning vasakul tiival eraldi komandopunkt; tulesektor kattis faarvaatri Naissaare ja mandri vahel. Positsioonini viib tänini munakivitee ning kaks helgiheitjat, millest üks asus Ilmandu küla juures, valgustasid öösiti merd.
