The Cypress of Catredal de Puebla. 2 of 3. The main altar, called the Cypress, was built between 1799 and 1819. It was designed by Manuel Tolsá, a well known architect. The construction was a huge project that took 20 years. It was blessed 05 December, 1819. The remains of many bishops are buried in crypts beneath the altar. The Cypress at 17.50 meters tall is built in a Neoclassical style, using different materials of Tecali marble, stucco, bronze, and cedar wood. The Cypress has a circular base with 16 columns. These columns surround statues of important church figures like Saint Gregory and Saint Augustine. The most important part is the bronze statue of the Immaculate Conception, which weighs 920 kilograms. The base of the Cypress has four small doors that lead to the bishops' crypts. The cathedral is located on the southern edge of the Zocalo de Puebla but has its side doors instead of its main doors facing the plaza. The current cathedral was built between the 16th and 17th centuries. It replaced an older church that stood in the same spot. It took 74 years to build, from 1575 until its dedication in 1649. The main entrance, called the Puerta del Perdón (Door of Forgiveness), was finished in 1664. The cathedral compliments the 1987 Puebla designation as a UNESCO World Heritage Site.
