The cathedral is built in a Gothic-inspired style, and it has a hidden trick. The main hall and its projecting side wings, called transepts, are laid out so that from the air the whole building looks like an enormous cross. Step inside and look up. The roof has no crossbeams holding it up. Instead, crossing vaults arch overhead like the keel of a ship turned upside down. That structure leaves the interior open, bright and spacious. Sunlight pours through the stained glass windows, which fill the hall with colour and a sense of grandeur. The numbers are impressive too. The grounds cover 1,400 ping, the interior rises to about 45 feet, and the seating area can hold around a thousand people. The church also has a story linked to China. Its planner, Father Fei Jishi, had earlier led the church in Yangzhou, and the Hsinchu building resembles the Sacred Heart of Jesus Cathedral there.
