Exploring the Ancient Walls of Itchan Kala: A Journey Through the Heart of Khiva, Uzbekistan
Itchan Kala, meaning 'inner town' in Uzbek, is the heart of the ancient city of Khiva, located in modern-day Uzbekistan. This fortified citadel, enclosed within towering brick walls up to 10 meters high, serves as a testament to the rich history and architectural prowess of Central Asia. In 1990, UNESCO recognized Itchan Kala as a World Heritage Site, acknowledging its significance as a well-preserved example of Islamic architecture in the region.
The origins of Itchan Kala date back more than 2,500 years, when nomadic tribes settled in the Khiva oasis. However, the city as it appears today took shape during the reign of the Khanate of Khiva, which flourished from the 16th to the 20th centuries. The city's strategic location along the Silk Road made it a crucial stopover for traders traveling between China, India, Persia, and Europe.
One of the most striking features of Itchan Kala is its imposing defensive walls. These walls, constructed from mud bricks and gypsum, were designed to protect the city from invaders. They encircle the entire old town, creating a labyrinthine network of narrow streets and courtyards that reveal a wealth of historical and cultural treasures. Within these fortifications lies a collection of over 50 historic monuments and 250 old houses.
Within these walls lies a collection of remarkable buildings, including the Djuma Mosque, one of the oldest and most significant religious sites in the city. Originally founded in the 10th century and largely reconstructed in the late 18th century, this mosque is famous for its flat roof supported by 213 carved wooden columns. Standing over 56 meters, the Islam Khodja Minaret, the tallest minaret in Khiva offers breathtaking panoramic views of the citadel upon climbing its spiral staircase. Its alternating bands of dark green and blue tiles make it the most recognizable landmark in the city.
Itchan Kala is also home to numerous mausoleums, madrasas, and palaces. Among them, the mausoleums of Pahlavan Mahmud and Muhammad Amin Khan stand out. The former houses the remains of Pahlavan Mahmud, a legendary hero known for his extraordinary strength and bravery, while the latter is the final resting place of Muhammad Amin Khan, who ruled Khiva from 1845 to 1855. His reign was cut short in battle, leaving the iconic, turquoise-tiled Kalta Minor Minaret famously unfinished.
Among the palaces, Tash-Khauli (the Stone House), built in the 1830s by Alla-Kulli-Khan, showcases the peak of Khivan decorative art. Its courtyards are adorned with elaborate blue-and-white majolica tiles, intricate wood carvings, and delicate stucco.
Overall, Itchan Kala provides visitors a captivating glimpse into the past and unparalleled insight into the culture, history, and architecture of Central Asia. Its designation as a UNESCO World Heritage Site is well-deserved, ensuring the preservation of this unique and enchanting destination for generations to come.
UNESCO Description of the World Heritage Site
Itchan Kala is the inner town (protected by brick walls some 10 m high) of the old Khiva oasis, which was the last resting-place of caravans before crossing the desert to Iran.

Human-Centric Planning of Traditional Islamic Settlements: A Space Syntax Study of Itchan Kala, Khiva
Itchan Kala, a UNESCO World Heritage Site in Uzbekistan, exemplifies the enduring effectiveness of Islamic urban planning principles. The study reveals that its spatial organization harmoniously balances communal interaction and seclusion through a compact yet hierarchically layered structure. Key findings include a highly integrated main market street anchored by the Juma Masjid, promoting commerce and worship, while residential quarters offer low visibility and high controllability for privacy. Madrasas, now museums, serve as transitional zones between public and private realms. The research employed axial and visibility graph analysis (VGA) at global and local scales to assess visibility, integration, and controllability, demonstrating the city's resilience across generations and socio-political transitions. Itchan Kala serves as a timeless model for human-centered, sustainable urban development.

Termite Control Strategies in Khiva and Khorezm: Traditional Practices vs. Modern Approaches
Research in Khiva and Khorezm reveals that traditional termite control strategies, rooted in vernacular architecture, have effectively reduced infestation risks for centuries. Historic buildings like those in Itchan Kala utilize baked bricks, treated timber, and moisture-control techniques, which inherently deter termites without relying on explicit ancient termiticides. Modern Uzbek research has built upon this local knowledge by developing 'toxic bait' capsules using poplar sawdust and locally-sourced cellulose feed, as well as biologic traps derived from over 40 native plants, both showing promising results in field tests. This study bridges traditional practices with modern approaches, offering sustainable solutions for heritage conservation while leveraging indigenous materials.

The colonialism of the Modern Movement and the
post‐USSR reaction in Central AsiaThis study reveals how modernist architectural language, originally rooted in socialist ideals, was repurposed as a tool of colonial control in Central Asia. It demonstrates that the Soviet Union's nomination of Itchan Kala as an 'open-air city museum' for UNESCO World Heritage status in 1990 reflected a broader strategy to displace local identities tied to empire and religion, while simultaneously preserving a sanitized version of history. Post-Soviet reactions in Central Asia, particularly in Uzbekistan, have shifted toward reclaiming narratives through the inscription of properties like Shakhrisyabz, Bukhara, and Samarkand, emphasizing social, cultural, and economic processes over mere architectural monuments. The research combines political science and historical analysis to explore how urban fabric and language were manipulated to serve colonial agendas, while also examining the challenges and opportunities in postcolonial conservation efforts.

Structural Health Monitoring of the Juma Mosque in Itchan Kala in Khiva (Uzbekistan): Laser Scanning Combined with Numerical Modelling
A collaborative structural health monitoring (SHM) project at the Juma Mosque in Itchan Kala, Khiva, Uzbekistan, reveals critical insights into the minaret's geometric anomalies and stability. Using terrestrial laser scanning (TLS), researchers captured high-resolution 3D point clouds, demonstrating that the minaret approximates a truncated cone with measurable residual inclination and taper. This approach combines TLS with planned in-situ measurements—such as accelerometers for resonant frequency analysis, position transducers, and thermocouples for thermal expansion and crack monitoring—to create a comprehensive SHM framework. A preliminary finite-element (FE) model, calibrated to the scanned geometry, will guide future restoration efforts by evaluating intervention efficacy. This study underscores TLS's potential in preserving UNESCO World Heritage Sites by integrating advanced monitoring with numerical modeling.
