Hi @helga19,
Yes, Plovdiv has definitely changed a lot since your last visit!
As @KlaudiyaG mentioned (thank you for the tag!), there are going to be a lot of festivals, concerts, performances, exhibitions, and other cultural events in Plovdiv this year. You can pick whichever you like and plan a visit around that time. The city is beautiful every month of the year, even though I recommend visiting in early spring and throughout autumn. It can get very hot during the summer! ?
Some of the events that I won’t miss this year are Ayliak parade in May and the NIGHT/Plovdiv in September. During the NIGHT, most galleries, museums and theatres are open to the public, and there are many artistic programs in various locations.
The Ayliak parade is organised by the Fire theatre, and there are going to be some breathtaking performances with fire.
Hope to have you again in Bulgaria soon, Inga!
