The huge triangular main gate of the school is the most widely known monument to represent Seoul National University. The main gate became a symbol of the university when the school moved to its current location in Sillim-dong in 1975. It was based on a sketch from a student of the university majoring in art. Designed with the first consonants of each word of 국립 서울 대학교 in Korean, the gate resembles the shape of a key. The key symbolizes the school’s determination to pursue the virtue it states in its motto ‘Veritas Lux Mea.’ The gate was refurbished in 2006 to celebrate the university’s 60th anniversary.
The color was changed from yellow to a light silver gray, and lights were placed around the gate to illuminate this famous structure in the nighttime. These changes were made to signify that Seoul National University is an educational facility welcoming all and to underscore the university’s role as the leading hall of learning moving forward day and night. Serving as the school’s landmark, the main gate shines throughout the night as the key to pursuing virtue.
