In a written reply to a question, Culture Minister Mahesh Sharma, however, said, there has been "no discernible change" in the income from entry fee in these monuments during the last few years.
"The revenue earned through entry fee from various ASI protected monuments during the year 2014-15 is Rs 93.38 crore," he said.
Sharma said fee for ticketed monuments have been increased with effect from April 1 this year.
The government had effected a three-fold hike in the entry fee for 116 monuments under the ASI for domestic visitors and 100 per cent for foreign tourists.
For monuments other than World Heritage Sites, the fee was increased three-fold to Rs 15 from Rs 5 for domestic visitors, while foreigners Rs 200 from Rs 100.
