When we discuss diseases and factors that affect humans, we cannot isolate architecture and the built environment. Over the years, architecture has been one of the most growing elements in the cities and any country development is measured by it, the fact that most countries are proud of the development and the rapid growth of their businesses. Healthy cities are continually creating and enhancing the physical activities and social environments that to expand resources that enable people to support each other and maximizing their potential. WHO listed the aims of a healthy city:

• To create a health-supportive environment
• To achieve a good quality air
• To provide basic sanitation and hygiene needs
• To supply access to health care

That being said, it is essential to provide good infrastructure to achieve this level of a healthy city rather than focusing on improving the political, economic and social arenas(“WHO | Healthy Cities,” 2019)

Galway Healthy Cities, which has been a member of the World Health Organization (WHO) European Healthy Cities since 2006, aims to establish an effective program that puts the health and social-economic and political agenda of all agencies. One of their main themes is to strengthen communities by building supportive healthy urban planning and design that includes housing and regeneration and so on(Galway Healthy Cities Projects, 2018). Although the organization’s main aim is Galway City, it purposes an initiative framework that helps designers to promote urban planning and tackling public health priorities.

The research of (Davies & Kelly, 2014) highlighted the importance of healthy cities and the need for multiple instruments to evaluate the strategies, the research also talked about the qualitative non-oriented approaches to evaluate the outcome. It was until the nineteenth century that realizes how important the provision of roads, housing and water supplies and the focus of medical attention in a modern way; the rapid industrial revolution and urbanization that resulted in human factory waster and pollution.
