On the quiet summit of Huayuanshan in Wuchang, a modest brick-and-wood chapel stands as a physical record of shifting eras. Completed on Easter Sunday in 1888, this Romanesque structure was designed and supervised by Bishop Epiphane Carlassare. Its construction followed the 1868 arrival of Italian nuns from the Canossian Daughters of Charity, who came to establish medical programs at the nearby St. Joseph Clinic.

The building occupies a footprint of one hundred and fifty square meters, with a long-hall layout of one hundred and thirty square meters. Its exterior walls of rustic brick masonry bear the physical scars of wartime shrapnel and decades of weathering. Long arched windows pierce the thick walls, once casting light on statues of the resurrected Jesus, Saint Joseph, and the Virgin Mary.

The custodians of this chapel changed with the tides of twentieth-century history. In 1926, the Canossian Sisters moved their headquarters to Hankou, leaving the chapel to the Sisters of St. Joseph. In late 1948, as foreign nuns were being repatriated, the Chinese Sisters of Christian Doctrine assumed management of the chapel. By 1951, the local government took control, ending the building's religious functions. During the late 1950s, hospital workers stacked medicine crates inside it, repurposing the sacred hall into a warehouse for the Hubei College of Traditional Chinese Medicine.

In February 2005, the city designated the chapel as a Second-Class protected historic building. Today, it has found a surprising second life. Reopened in August 2023 as the Blue Butterfly Art Museum, the interior is saturated in deep Klein blue. The walls display over two hundred species of preserved butterflies, including the emerald swallowtail and the transparent glasswing. Outside, a staircase wrapped in fifty thousand artificial red roses leads visitors up the hillside. The scent of old timber blends with the visual shock of modern art, inviting visitors to observe the scarred brickwork and contemplate a century of survival.
