Modular geometric volumes and chromatic gathering nodes fill a historic courtyard in Istanbul. For eleven days in autumn 2026, they guided families through the Rami Library grounds. Turkish practice Milimetrik Architects designed AileFest 2026, a temporary intervention that covered 91,000 square meters of the historic site.

The festival ran from September 26 to October 6, 2026. According to the project description, roughly 825,000 visitors attended. The program combined family recreation, education, and cultural events across the outdoor courtyards and the library’s interior halls.

Open-ended play across the courtyard

Milimetrik avoided fixed play equipment. Instead, the studio filled the courtyard with modular geometric volumes, low abstract shelters, and brightly colored gathering points. Visitors decide how to move through them and what to do once they arrive.

Temporary structures can also reshape a public space with bold color and a light footprint. Riyadh’s BAG Café Turns Parking Lot Into Tents shows how scaffolding and tents create a similar pop-up sense of invitation.

The pieces are built at several heights so that small children and older visitors can both use them. Many of the modular volumes are finished in bold, chromatic colors. Their scale keeps them readable from a distance and comfortable to sit on up close.

Abstract shelters give visitors places to pause and use the courtyard spontaneously. Abstract shelters give visitors places to pause within the courtyard.

Indoor reinterpretation of the book fair

Inside the library, the Book Fair departs from the standard grid of exhibition booths. Pitched, house-shaped pavilions in primary colors stand among modular display units. Graphic patterns on the floor guide visitors between stands.

The layout creates continuous movement between the open courtyards and the historic galleries. Visitors pass from sunlight to shaded halls without a formal threshold. The temporary structures are built from timber and steel and sit on the site without altering the building’s heritage fabric.

Balancing play and heritage at Rami Library

The temporary installation in the courtyard shapes how visitors move through the site. The modular volumes sit within the historic site without altering its heritage fabric. The effect is playful, yet the entrance remains clearly legible as a civic building.

Reusing a historic civic site for new public life raises similar questions about balance. Decommissioned Power Stations Reborn as Public Spaces surveys how former industrial landmarks took on fresh civic roles.

The project shows that a heritage site can host a large public program without permanent alteration. Temporary construction carried the weight of the festival, and the historic buildings stayed intact. For cultural institutions weighing similar events, the Rami Library offers a clear model of scale, color, and restraint working together.
