Well, it’s apparent from the name itself. If you are a bookworm and you have travelled all the way to Sofia, the open-air book market is a must-visit in the city. This is a great place to get rare books that speak volumes on Bulgarian history, culture and cuisine. In short, it’s a place from where a traveller can get books that will give them a deeper understanding about the destination. Also available in plenty are novels written by Bulgarian authors over the years, which give travellers a chance to delve deeper into the literary history of the place.
