The Republic of Moldova is a small country, but its cultural treasure is rather rich:

Personally, I find the word 'treasure' here perfectly sensible - but the more common word would probably be 'wealth', "...cultural wealth is rather rich"

habits inherited from our ancestors, in this context, 'customs' is more natural, customs inherited...

very beautiful traditions, I especially I like [лучний порядок слов] those_that are related to winter holidays - Christmas carols, "plugusorul" and "sorcova". So, in order to describe a musical event in my country, I will mention the festival "Colinde, Colinde" [Colinde here is the proper noun, so "the festival (of)" does not need capitalisation]. Different choirs from Moldova and other countries take part in [take part in] this festival and they sing very beautiful Christmas carols. The event occurs in the Organ Hall in Chisinau, (that is) the capital of Moldova, in the last week of December. I have never been at this festival['never been at' is grammatically correct, but the more common phrase is "have never been to such-and-such event..."], but I always watch it on TV. I enjoy it very much, because when I listen to the carols, I refresh my soul and on the eve of (the) winter holidays it is marvelous.
However, in December I am going to leave everything on/to one side and to go to this festival.
