The figures were released after a Freedom of Information (FOI) request from the 'Huffington Post UK'. The House of Commons authorities acknowledged that users of the Parliamentary Network servers have repeatedly attempted to access websites classed as pornographic between May 2012 and July 2013.
It remains unclear whether Members of Parliament, peers or other staff are responsible, House of Commons officials said.
According to the figures, the number of attempts to access pornographic websites through the parliamentary network was 114,844 in November 2012 and 55,552 in April 2013.
At least 5,000 people are estimated to be working on the parliamentary estate.
However, Parliamentary officials indicate that the figures would be inflated by websites automatically refreshing and thus adding to recorded access attempts. Additionally, pop-up or embeddable content like videos and pictures could have a knock-on effect on the number of attempts recorded.
British Prime Minister David Cameron had announced in July that most households in the UK would have pornography blocked by their internet provider unless they chose to receive it as part of an overall crackdown.
UK's biggest internet service providers have agreed to the filters scheme meaning it should cover 95 per cent of homes.
