Rome has had an enormous influence on European art and art history for over 2,000 years. Indeed, the city was the birthplace of the foundations of western architecture. This architectural guide encourages visitors to go beyond the most frequently visited historical landmarks to explore the hidden architectural pearls of Rome. The focus is on unusual - yet less-known - buildings that were built from the second half of the 20th century onwards. From cultural and educational institutes, sport facilities, and residential buildings to sacred and mixed-use buildings through to transport infrastructure: this book presents 140 projects that cover a wide range of architectural styles and typologies.
