Archaeological proof of temple destruction is mostly found in broken remains, inscriptions, and records from that time. When archaeologists dig old temple sites, they find damaged idols, scattered stones, and foundation walls that show signs of being pulled down.
For example, at Somnath temple, there are many layers which shows how it was destroyed and then rebuilt again and again. Same is seen in Kashi Vishwanath temple where Mughal time mosques stand on temple base. Inscriptions also talk about kings destroying temples, like in some Persian texts which celebrate victories.
Sometimes even the change of architecture tells us. Like when you see temple pillars inside mosques, you understand that they were reused after destruction.
Archaeology also uses carbon dating and other tests to show the age of stones and sculptures. This proves which part belongs to which period. So yes there is evidence, but historians debate how much of it was political or religious. Some say temples were broken to show power, while others argue it was just war spoils. But archaeology gives strong physical proof like smashed idols, reused carvings and historical layers.
These proofs are very important to understand what really happened in past, because written records alone may be biased.
