Lack of Town Planning in the City of Ur
The city of Ur, located in ancient Mesopotamia, lacked proper town planning which is evident from various aspects of its urban layout.

Absence of Grid System
One of the key indicators of the lack of town planning in Ur was the absence of a grid system for laying out streets and buildings. Unlike many other ancient cities like Mohenjo-daro or Harappa, Ur did not have a planned layout of streets and structures.

Haphazard Construction
The buildings in Ur were constructed in a haphazard manner without any uniformity or planned design. This led to a chaotic urban landscape with irregularly shaped structures crammed together.

Lack of Infrastructure
The city lacked proper infrastructure such as sewer systems, drainage, and sanitation facilities. This lack of basic amenities contributed to unsanitary conditions within the city.

Lack of Public Spaces
There were no designated public spaces like parks or squares in Ur where people could gather or engage in communal activities. This further highlights the absence of urban planning in the city.

Conclusion
In conclusion, the city of Ur lacked town planning which is evident from its disorganized layout, haphazard construction, lack of infrastructure, and absence of public spaces. This lack of planning had long-term implications on the urban development and livability of the city.
