  Boris' Garden (Borisova Gradina), named after Tsar Boris III, holds the distinction of being the oldest and largest park in Sofia, often referred to locally as "The Lungs of Sofia". Its development began in the 1880s, designed by Swiss gardener Daniel Neff, establishing it as a foundational green public space in the newly formed Bulgarian state. This popular park is much more than a natural retreat; it is an integrated urban space featuring lakes, numerous monuments to prominent Bulgarians, and diverse plant life. Crucially, Boris' Garden is home to the historic University Astronomical Observatory, which will be our next stop.
