Lenuzzi's Horseshoe, Park district in Donji Grad, Croatia

Lenuzzi's Horseshoe is a U-shaped band of squares and parks in Donji Grad, Zagreb, formed by seven squares aligned on three straight lines, with the Zagreb Botanical Garden connecting the two ends. Inside the U lie two further squares, Petar Svačić and Petar Preradović. The band is bordered by multi-storey buildings with light facades and red tiled roofs, and the enclosed interior holds tightly packed city blocks.

Architect Milan Lenuci designed this green space in the late 19th century as part of modernizing Zagreb according to European standards. The project connected the expanding city with green corridors modeled on contemporary European urban planning.

Major cultural institutions like the Croatian Academy of Sciences and Arts and the National Theater occupy historic buildings throughout the space. These venues shape how locals and visitors experience the area as a center for arts and intellectual activity.

The central location provides direct access to coffee shops, restaurants, museums, and public transportation throughout the Lower Town district. Pathways between the parks are clearly marked, making it easy to explore all areas.

The horseshoe's two open ends were joined only in 1889, when the newly opened Zagreb Botanical Garden closed the U. The fitness park in Grgur Ninski Street, between the Botanical Garden and the Esplanade Hotel, dates from June 2013. In September 2013 the horseshoe received a special award at Entente Florale, while Zagreb took silver.
