Hegra Fortress (Norwegian: Hegra festning) is a small mountain fortress in the village of Hegra in the municipality of Stjørdal in Trøndelag county, Norway. Originally known as Ingstadkleiven Fort (also Ingstadkleiva Fort), it was built between 1908–1910 as a border fort as a defence against the perceived threat of a Swedish invasion.[4]
