The building of the breathtaking building started in 1985 and was completed in 1899, because of a land grant in the Government of India.The cathedral has been through a whole lot.  It survived the 1930 Rangoon earthquake having hardly any harm.   The 1944 allied invasion of Rangoon (since Yangon was known back then) led to the harm of St Mary's lovely stained glass windows.  Yet more, at 2008, St Mary's stained glass windows have been hit by Cyclone Paris, which killed at least 146,000 people around Myanmar.St Mary's Cathedral is located on 15 acres of property, and you'll be in awe at the sheer size and beauty of this.  The red brick construction has twin spires which dominate the skies.  The detail from the stained glass windows really are amazing, as is the structure of the balconies.We visited St Mary's through lunchtime, so we weren't able to see indoors, which is reported to be utterly stunning.  But, we did spend a reasonable bit of time walking round the palace, taking from the many religious statues, architecture and flowers.St Mary's Cathedral is quite well-kept.  There were plenty of employees taking care of upkeep on the grounds and surrounding buildings, and the grounds were clean.  It had been really silent and peaceful when we moved, and I would certainly recommend a trip as a getaway from the hustle and bustle of downtown Yangon.The cathedral Provides everyday masses by Father Dominic Thet Tin and Father Paulus Eh Dho Kyaw.   On Sundays it is possible to attend English masses at 6am and 5pm, and Burmese mass at 5pm.
