Ngang Pass - A historic gateway on the Hoanh Son Range. Ngang Pass is located on the Hoanh Son Range, in Hoanh Son Ward, Ha Tinh Province. The pass connects the mountains to the sea, with a winding road across the mountainside that creates a landscape characterized by steep gradients, depth, and expansive vistas. The summit is home to Hoanh Son Quan (Hoanh Son Gate), a structure built in 1833 during the reign of Emperor Minh Mang. Hoanh Son Quan serves as a remnant of the Nguyen Dynasty's traffic control system across Hoanh Son, possessing significant architectural, historical, and cultural value. The structure is built of stone, integrated into the natural topography of the mountain. The Ngang Pass area is also deeply connected to literary tradition, famously immortalized in the poem “Qua Deo Ngang” (Crossing Ngang Pass) by Ba Huyen Thanh Quan. Regarding film production potential, the location offers mountain backdrops, winding mountain roads, an ancient gateway, and coastal views, making it suitable for historical-cultural films and documentaries focusing on heritage, history, and the geography of Central Vietnam.
