Fact-Check: "The Eiffel Tower Grows Every Year"

What We Know

The claim that "the Eiffel Tower grows every year" can be understood in the context of both thermal expansion and structural modifications. The Eiffel Tower, which stands at 330 meters (1,083 feet) including antennas, was originally completed in 1889 at a height of 312 meters. Over the years, additional antennas have been added, contributing to its overall height. For instance, antennas were added in 1957, 2000, and 2022, which increased its height incrementally (Eiffel Tower).

Moreover, the structure experiences seasonal changes due to thermal expansion. According to the Eiffel Tower's official website, the metal structure can gain or lose a few centimeters throughout the year. Specifically, during summer, the tower can expand by up to 15 centimeters (approximately 6 inches) due to heat, while it contracts in winter, losing a similar amount (Why does the Eiffel Tower change size?). This phenomenon is a result of the physical properties of iron, which expands when heated and contracts when cooled (India Today).

Analysis

The claim is partially true as it hinges on two main aspects: the addition of antennas and the effects of thermal expansion. The Eiffel Tower indeed grows taller each year due to the installation of new antennas, which is a factual and verifiable statement. However, the growth attributed to thermal expansion is not a permanent increase in height but rather a temporary change that fluctuates with the seasons.

The sources used to support this claim vary in reliability. The Eiffel Tower's official website is a primary source and provides accurate information about the structure's height and the reasons for its seasonal changes (Eiffel Tower). Other sources, such as India Today and Independent, corroborate the thermal expansion phenomenon, explaining how the tower's height can change with temperature variations. However, some articles may simplify the concept, leading to misconceptions about the nature of this "growth" (The Travel).

While the information is scientifically sound, the interpretation of "growing" can lead to confusion. The seasonal changes are imperceptible to visitors and do not affect the structural integrity of the tower (Why does the Eiffel Tower change size?). Therefore, while the claim has a basis in fact, it requires careful framing to avoid misleading implications.

Conclusion

The verdict on the claim "the Eiffel Tower grows every year" is Partially True. The Eiffel Tower does experience changes in height due to thermal expansion and the addition of antennas. However, the growth attributed to thermal expansion is not permanent and varies seasonally, which can lead to misunderstandings about the nature of the claim. Thus, while there is a factual basis for the claim, it is essential to clarify the context in which the growth occurs.
