二沙灣砲台又名海門天險，為國定古蹟，位於中正公園二沙灣山上，採用傳統的中式城門築法，依山而建，氣勢雄偉。
原位於二沙灣海邊的砲臺，創建年代約在清道光年間（西元1840年），之後砲台被毀，現址為劉銘傳部隊於清法戰爭後（西元1885年）所建，深具歷史價值。二沙灣砲台屬高地砲台中的「抱山式砲台」，不同於一般砲台，砲台建在地勢較高的臨海山頭，營盤設計在背海面地勢較低之處，海上來犯敵艦的砲彈只會打到山崗向海的一面，或越過山頭落到谷底，很難擊中營區。其與位於外海口門的社寮、白米甕構成鐵三角防禦網，防守基隆內、外港。
二沙灣砲台現存建築，如城門、營舍牆基、大階梯、砲座、子牆及儲彈藥庫，各有其特色；砲座、子牆均使用鐵水泥建造而成，另砲台區內並有仿製之古砲數門；又因居高臨下，視野寬廣，遊客可於砲座俯瞰港口，體會「海門天險」的氣勢，景觀絕佳。砲台全區步道林木密佈，其間有鳥類及昆蟲，可在參觀古蹟之餘另有一生動自然之美。
Ershawan Fort is also named "Haimen Tiansian" which means a very dangerous gate to the ocean and is located on the top of Ershawan Mountain near the east harbor of Keelung. Following the traditional construction method to build the city gate, the front door of the platform was built by stones along the mountain, which is very splendid. The strategic value of the fort explains why it was chosen to be a military base during the Qing dynasty. Visitors can view Keelung Harbor from the fort to feel its significance. Today, it is a national historic site. The walls of the main entrance to the fort are made of stones laid using the technique traditionally used to build city gates in China. Over the arched doorway are the characters Hai Men Tian Xian. The gate, barracks, steps, gun platforms, ammunition stores, and other structures still remain. The fort has great significance in national defense history.
