NCERT Class 5 EVS Chapter 10: Walls Tell Stories

The Architecture and Defense of Golconda Fort

Golconda Fort is a marvel of medieval engineering. Built on a granite hill, the fort features thick, massive outer walls designed to withstand enemy attacks. The outer wall has 87 bastions (also known as burj). Bastions are round, protruding sections built into the fort's walls that are higher than the rest of the wall. This unique design served a critical defense purpose: soldiers standing inside the bastions could peek through small openings or holes. This gave them a wide, panoramic view of the surrounding terrain without exposing themselves to enemy fire. Additionally, the grand gates of the fort were fitted with sharp iron spikes. These spikes prevented enemy armies from using elephants to smash open the heavy wooden gates, making the fort nearly impenetrable.

How Water Was Lifted: The Ancient Water System

1. Step 1: Sourcing from Deep Wells — Water was collected from large stepwells (baolis) and reservoirs situated at the ground level of the fort.
2. Step 2: Using the Persian Wheel (Rahat) Mechanism — Bulls or oxen were harnessed to a heavy wooden pole. As they walked in circles, they turned a large vertical gear wheel connected to a chain of buckets.
3. Step 3: Elevating the Water — The rotating bucket chain dipped into the well, scooped up water, and transported it upward, emptying it into a collection trough at a higher level.
4. Step 4: Gravity-Fed Clay Pipes — From the elevated troughs, water flowed through an intricate network of clay pipes embedded in the fort's walls to supply gardens, fountains, and royal palaces on the hilltop.

Important Historical Discoveries & Life in the Fort

• Living Communities: The fort was not just for kings and soldiers. It was a bustling township where farmers, craftspersons, and merchants lived and worked.
• Bronze Technology: Many heavy cannons and statues found in the fort were made of bronze. Bronze is a durable alloy made by mixing copper and tin, which is stronger than copper alone.
• Royal Cannons: Large cannons were used by rulers like Aurangzeb during attacks, though some sieges lasted for months because the fort's walls were too strong to breach.
• Museum Preservation: Museums store ancient artifacts like pottery pieces, jewelry, utensils, and old weapons. These relics tell us what people wore, ate, and crafted in olden times.

Exam Tips: Avoid Common Mistakes!

1. Bronze vs. Brass: Don't confuse these two alloys! Bronze is a mixture of copper and tin, whereas Brass is a mixture of copper and zinc. EVS exams often test this specific distinction.
2. Why Bastions have Holes: Remember that the holes in the bastions were for safe observation and shooting. Simply saying 'for air/ventilation' is incorrect and will lose you marks!
3. Map Reading: Learn the cardinal directions (North, South, East, West) to answer map-based questions about Golconda Fort's layout.

Practice Questions with Solutions

• Q: Why were bastions (burj) made round and tall in the fort wall? A: Step 1: Analyze the purpose of a bastion. Bastions are designed to provide a wider viewpoint. Step 2: Understand the circular shape. A round shape allows soldiers to look out in multiple directions (left, right, and front) easily. Step 3: Understand the height. Being taller than the main wall allows soldiers to see enemies approaching from far away. Final answer: Bastions were made round and tall to give soldiers a wide viewing angle and a safe height to spot approaching enemies from a long distance without being seen.
• Q: Why were big iron spikes fixed on the huge gates of the Golconda Fort? A: Step 1: Identify the main threat. In ancient battles, enemy kingdoms used war elephants to smash open fort gates. Step 2: Explain the countermeasure. Placing sharp, massive iron spikes on the wooden gates made it impossible for elephants to push or strike the gates with their heads. Final answer: Big iron spikes were fixed on the gates to prevent enemy elephants from battering and breaking open the heavy doors of the fort.
• Q: What is the difference between copper and bronze? How were they used in the fort? A: Step 1: Define copper. Copper is a pure, natural metal that is relatively soft. Step 2: Define bronze. Bronze is an alloy, which is a mixture of copper and tin. It is much harder and stronger than pure copper. Step 3: Link to their usage. Because of its strength, bronze was used to manufacture heavy cannons, strong weapons, and durable statues inside the fort. Final answer: Copper is a simple metal, while bronze is a stronger alloy made of copper and tin. Bronze was preferred for making heavy-duty items like cannons and defense weapons.
• Q: How do things kept in a museum help us understand the past? A: Step 1: Identify what is kept in a museum. Museums house old pottery, weapons, clothes, coins, and paintings. Step 2: Connect artifacts to historical facts. By looking at these items, we learn about the daily lifestyle, food habits, clothes, technology, and artistic skills of people who lived hundreds of years ago. Final answer: Museum items serve as physical clues that help us reconstruct history and understand how ancient civilizations lived, worked, and dressed.
