the then-newly canonised saints because it was the most thematically similar, in that the martyrs gave up their lives for the faith, emulating Jesus' sacrifice to save mankind. New stained glass windows were installed depicting the saints. Crypt A crypt was constructed beneath the former Chapel of St. Anthony in 2009 to house the remains of former bishops of Hong Kong. This consists of two vicar apostolics, Timoleon Raimondi and Dominic Pozzoni, and five of the six deceased bishops – Enrico Valtorta, Lorenzo Bianchi, Francis Hsu, Peter Lei, and John Baptist Wu. Bianchi's remains were interred later than the others (apart from Wu) due to the fact that he was buried in Milan. Thus, the diocese had to apply for permission to allow for some of his remains to be transported back to Hong Kong; the request was eventually granted. Wu's remains were interred in September 2022, twenty years after his death, while the remains of Michael Yeung are buried at St. Michael's Catholic Cemetery in Happy Valley. The inspiration for the crypt came from the design of a traditional Chinese family house, which would contain the remains of ancestors. The bishop at the time, Joseph Cardinal Zen, felt that the crypt would be a "symbolic move to inherit the teachings of previous generations in order to inspire future ones." Because the cathedral is a Grade I historic building, prior approval had to be obtained from the Buildings Department before any construction work could be carried out. Treasures Relics of the Chinese Martyrs Shortly after the canonisation of the 120 Chinese Martyrs on 1 October 2000, the relics of sixteen of them were placed at the Chinese Martyrs' Chapel (formerly the Chapel of Our Lord's Passion). They are stored in a relic box – designed locally by Sister Paola Yue – that is situated at the foot of the side altar. Relic of Pope John Paul II In November 2011, a lock of John Paul II's hair was brought to the cathedral after the Holy See granted the Diocese of Hong Kong a relic from the late pontiff. The diocese had earlier requested this, since they felt this would symbolically accomplish the Pope's longtime dream of visiting China. He had constantly stated his intent of visiting the country, but never did so due to the longstanding tensions and strained relations between China and the Holy See. Bishop John Tong Hon
