The Elegance Above: Symbolism and Beauty of Giwa, Korea’s Traditional Roof Tiles

Introduction

Look up at a traditional Korean building, and you'll see a crown of curved tiles gently cascading across the roofline—this is Giwa (기와), the soul of Korean rooftops. More than functional, Giwa is poetic. It tells a story of earth and fire, of harmony with nature, and of status, spirituality, and aesthetics. In this post, we explore the history, symbolism, and enduring appeal of Korea’s traditional roof tiles, and how they transform architecture into visual philosophy.

What is Giwa?

Giwa refers to fired clay tiles used to cover the roofs of hanok and palaces. Traditionally arranged in alternating concave and convex shapes—called Ogiwa (오지와) and Anjiwa (암지와)—these tiles lock together to shed rain, resist wind, and breathe with the building beneath.

The structure underneath the tiles, known as cheoma (eaves), curves upward like a smile or a crane in flight. This curve isn’t just beautiful—it reflects philosophical principles about openness, protection, and elevation.

History and Craftsmanship

Giwa-making dates back to the Three Kingdoms period, with Goryeo and Joseon dynasties refining the process. Each tile is handmade from clay, molded, dried, and fired in kilns. Artisans select clay based on mineral content and mold curvature to maintain uniformity. The result is both elegant and enduring—many ancient rooftops still survive today.

In large complexes like Gyeongbokgung or Bulguksa Temple, roofs were covered in black-glazed Giwa reserved for royalty and sacred structures, while commoners used unglazed versions with earthy hues.

Symbolism and Philosophy

In Korean culture, the roof is not just the "top" of a building—it is its spiritual ceiling. Giwa tiles symbolize:

  • Protection: Against rain, wind, and spiritual impurities
  • Order: The uniformity and layering reflect Confucian ideals of hierarchy and harmony
  • Nature: The curve of eaves mirrors the mountains, and the clay reflects the soil

Some eaves feature japsang (잡상)—small figurines like dragons, lions, and monkeys, each with symbolic meaning, often warding off evil or invoking good fortune.

Sound, Texture, and Light

When rain falls on a Giwa roof, it creates a soothing rhythm—a soundscape many Koreans associate with peace and home. The texture of the tiles, slightly rough and porous, absorbs and releases heat slowly, helping regulate interior temperatures.

Sunlight glides across the curved surfaces, creating dynamic shadows and highlights. The roof becomes alive with time, its colors deepening with age, its imperfections adding character.

Modern Uses and Interpretations

In today’s Korea, Giwa is being reimagined:

  • Modern Hanoks: New buildings use traditional tiles with modern insulation
  • Public Architecture: Museums, cultural centers, and schools often feature Giwa roofs as a nod to heritage
  • Interior Decor: Broken or reclaimed tiles are used in garden walls, flooring, or sculpture

Architects blend Giwa with concrete and glass, symbolizing Korea’s fusion of tradition and innovation.

Preservation and Education

Programs like “Hanok Stay” and cultural heritage workshops teach visitors how Giwa tiles are made and maintained. In Seoul’s Bukchon and Jeonju Hanok Village, residents restore rooftops using centuries-old techniques, preserving not only the architecture but the philosophy it embodies.

Government initiatives also support artisans, kilns, and apprentices to ensure that the art of Giwa continues to be passed down.

SEO Strategy & Content Opportunities

Content creators in travel, architecture, or culture can target keywords such as “Giwa roof design,” “Korean roof architecture,” “hanok roof tiles,” or “traditional Korean building materials.”

Combine blog posts with visual content like roof detail photography, time-lapse rain videos, or interviews with tile artisans. These create strong engagement while telling a deeper cultural story.

Conclusion

Giwa is more than a roof—it is a crown, a shield, a song. It shelters with elegance, speaks through silence, and watches over those who live beneath it. In every curve, there is a whisper of wisdom. In every shadow, a piece of history.

As Korea moves forward, the rooftops remind us to look upward—not just for shelter, but for meaning, beauty, and belonging.

From Kingdoms to Global Power: A Short History of Korea That Everyone Should Know Korean history is a tapestry woven with dynasties, philosophies, wars, and a deep-rooted cultural identity that has endured for thousands of years. To understand Korea's present — a nation renowned for its cultural exports, technological prowess, and democratic vitality — we must explore its remarkable journey from ancient times to the modern era. Gojoseon: The Legendary Beginning (2333 BCE – 108 BCE) Korea's historical narrative begins with Gojoseon, said to be founded by Dangun, a semi-mythical figure born from divine ancestry.

Gojoseon laid early foundations in bronze technology, law (the Eight Prohibitions), and regional trade, establishing itself as a formidable presence in Northeast Asia before falling to the Han Dynasty’s invasions.
