National Theatre, central park
There is a park in the middle of Sofia with a fountain (as seen here), and apparently it has different flower beds designed to represent different countries.
Anybody might walk through it, but a common sight is groups of old men sitting under trees playing chess. If you have the time to spare stop and watch a while.
New Year's Eve
New Year's Eve is a great holiday here. In Sofia, every year there is a free open-air concert in the square in front of the National Gallery. Usually it starts at 10 pm on Dec. 31 and ends in the early hours of Jan 1st. There are some pop and rock bands, folk music and dance, etc. A few minutes before midnight, they broadcast the President's speach to the nation, then the whole crowd counts down, at midnight they play the national anthem and everybody sings, then 'Mnogae Leta" and then everybody dances the horo. It gets quite crowded but there's a special festive spirit, and usually total strangers shake hands, hug, and dance the horo.
Meeting of 2007 was special, as Bulgaria entered the EU, there were two stages in stead of one, great fireworks, speaches, broadcasts, etc. For more details, check out the local customs on my Bulgaria page.
Blagoveshtenie (Annunciation, 25 March)
According to the Bible, on this day Gabriel brought the news to Mary. However, this day is also the closest to the Spring Equinox, and has fused many of the pagan & Christian rituals.
The lore says that on this day the cuckoo announces the approach of the summer; the bear wakes up from winter sleep, the snakes and lizards come out of their holes, and the samodivi (magic women rulers of the fields, forests and meadows) come back to their realms. Young unmarried women and girls are not allowed early out to avoid the samodivi (who might take away one's beauty and cause illness and death). One shouldn't touch needles (so no knitting, sewing, etc.) to avoid snake bites. The women also ritually circle the house, making noise with a pan, to scare away all the snakes, lizards, frogs, fleas, etc. After the spring cleaning, the rubbish & dust are burnt to cleanse from illnesses.
Boyana Church - on the UNESCO...
Boyana Church - on the UNESCO list of world treasures, this church was recently restored and more beautiful than any of the pictures you would ever see of it.
You can take a taxi from Sofia top the Boyana suburb, which costs about 3 leva ($1.50) and it takes about 10 minutes. On the way back you can take the 'route taxi' #21(in Bulgarian MARSHRUTNO TAXI), which will take you back to the center on the city at NDK.
You can see a nice photo of the interior of the church and read more historic information at this site http://www.sofiaecho.com/daytrips.php
There are other fun day trips mentioned on this site, but I did not go to any of those places.
