For over six centuries, a sentinel of wood and stone has stood at the heart of Liaocheng. This is Guangyue Tower, a structure born from military necessity and elevated into a poetic landmark. Its story began in 1374, when Commander Chen Yong, using surplus timber from the city walls, raised a watchtower to “observe the enemy and look into the distance.” They aptly named it "Yu Mu Lou"—the Surplus Wood Tower.

Crowned by a majestic four-eaved, cross-gabled roof, the main tower is a symphony of traditional carpentry. Its 33-meter height is achieved not with nails, but through an intricate skeleton of 192 main columns and over 200 sets of interlocking dougong brackets, all fitted together with tenon-and-mortise joints. Thirty-two "sky-reaching" columns form its resilient core, a design that has withstood the centuries. Resting on a massive 9-meter-high brick base with four arched gates, the tower’s imposing presence commands the landscape.

Its fame, however, stems from the imperial footsteps that have graced its stairs. The Kangxi Emperor visited four times, leaving behind a plaque inscribed with characters signifying the tower’s divine light reflected that of the sacred Mount Tai. His successor, the Qianlong Emperor, was an even greater admirer, ascending the tower on six of his nine visits to the region and composing thirteen poems in its honor. He was so captivated he designated it one of his 36 temporary palaces.

Despite numerous renovations across the Ming and Qing dynasties, the tower’s essential Ming character remains, a testament to the builders whose surplus wood and visionary skill created an enduring symbol. It stands today not as a relic, but as a living chronicle, its wooden bones whispering tales of emperors, poets, and the timeless city it guards.
