## Overview

The Baltic Way Memorial, situated in Riga, Latvia, commemorates a significant historical event in which approximately two million individuals formed a human chain spanning 600 kilometers to advocate for the independence of the Baltic States: Estonia, Latvia, and Lithuania. This site serves not only as a memorial but also as an interactive platform for education and reflection on the principles of peaceful protest and non-violent resistance.

## Spatial Strategy and Organization

The design features a linear gallery known as the "Line of Unity Gallery," which symbolizes the collective journey toward freedom. This gallery connects the capitals of the Baltic States—Tallinn, Riga, and Vilnius—thus reinforcing the shared historical narrative. The memorial is organized longitudinally, incorporating distinct areas that highlight milestones along the 600 km route, specifically the **0 Km Courtyard** and the **600 Km Courtyard**. The 0 Km Courtyard serves as the entry point, engaging visitors with historical narratives, while the 600 Km Courtyard represents victory and resilience, offering a space for contemplation.

Additionally, an **Amphitheater** provides a versatile venue for performances and community gatherings, further enhancing public engagement and creative expression within the memorial.

## Materiality and Sustainability

The architectural design integrates materials that reflect the memorial's ethos and commitment to sustainability. **Concrete** serves as the primary structural material, symbolizing strength and durability. It is utilized to create dynamic forms that endure environmental challenges. **Glass** elements are incorporated within the gallery to foster transparency and inclusivity, allowing for a shared experience among visitors.

Sustainable features include **Green Roof Systems**, which utilize living vegetation to improve air quality and aesthetic appeal, and a central **Water Feature** that reflects the natural landscape and connects to the Baltic Sea’s geographical and cultural significance. The use of **Geothermal Energy** systems throughout the site further underscores a dedication to environmental mindfulness, providing efficient temperature regulation. Additionally, **LED lighting** projects the flags of the Baltic States onto the water's surface at night, offering a visual representation of unity and national identity.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
