In the layout of Harappan cities, the 'Citadel' typically refers to:

Correct Option

The correct option is

The smaller, raised fortified area located to the west.

Explanation

Harappan urban planning is renowned for its standardized layout. A distinctive feature of most Indus Valley Civilization cities was their division into two distinct parts: the Citadel (or Acropolis) and the Lower Town.

Detailed Analysis

• The Citadel (West): This section was typically located to the west. It was smaller in area but built on raised mud-brick platforms, making it physically higher than the rest of the city. It was often fortified with walls to separate it from the Lower Town. The Citadel housed key administrative and public structures, such as the Great Bath, granaries, and assembly halls.
• The Lower Town (East): This section was located to the east. It was much larger in area but lower in elevation. This zone was primarily residential, housing the common populace, and featured the characteristic grid system of roads and drainage.

Therefore, the description of a "smaller, raised fortified area located to the west" accurately defines the Citadel.

While this bipartite division is the norm (e.g., Mohenjo-Daro, Harappa, Kalibangan), exceptions exist. For instance, Dholavira was divided into three parts (Citadel, Middle Town, and Lower Town), and Chanhudaro lacked a citadel.

Key Takeaway: In the standard Harappan layout, the Citadel is the western, raised, and fortified sector associated with the ruling class and public institutions, distinct from the eastern, larger Lower Town used for common residence.
