What are the top three schools of architecture and where they located?

There's no single definitive "top three" architecture schools globally, as rankings vary depending on the criteria used (faculty, research output, employment rates of graduates, etc.). Different publications produce different rankings.

However, three schools consistently appearing near the top of most reputable architecture school rankings are:

1. Massachusetts Institute of Technology (MIT) School of Architecture and Planning: Located in Cambridge, Massachusetts, USA.

2. Harvard University Graduate School of Design (GSD): Located in Cambridge, Massachusetts, USA.

3. Architectural Association School of Architecture (AA): Located in London, England, UK.

It's crucial to remember that many other excellent architecture schools exist worldwide, and the "best" school for a particular individual will depend on their specific interests, learning style, and career goals.
