While visiting the monasteries, remember you are in a sacred place. Dress modestly, with legs and shoulders covered, to show respect for the local customs and faith. Keep your voice low to preserve the peaceful ambiance and adhere to any photography restrictions to respect the privacy of the monks.
I've had some people ask me, so I thought I'd start a post about etiquette. If you are out taking tours and you don't dress properly, be sure to look for a scarf or skirt (for the ladies) that they may provide to make you respectable enough to enter the space. It's far better, though, to dress properly in your own wardrobe!
Loud talking is a no-no. It's also a good idea to observe Orthodox customs when entering the sacred space, even if you aren't Orthodox. Non-orthodox may venerate icons, light candles, submit prayer requests, etc.
Can anyone think of anything else to add?
