The number of visitors to the Centre - excluding those attending performances - reached 1,046,958 in 2011, up 3.1% on 2010.
The figures released from the annual Survey of Visits to Tourist Attractions in Wales show that Swansea’s LC is in second position and was the most visited attraction with paid admission in Wales. A total of 708,180 people went through LC’s doors last year, an increase of 9.1% on 2010 when it attracted 649,053 visitors.
St Fagans National History Museum was in third overall position with 610,074 visitors which is virtually unchanged from 2010.
The survey shows that last year 15.8 million people visited the 214 attractions that participated in the survey, with visits to free attractions representing over half (57%) of all visits.
Business Minister Edwina Hart said:
"Tourism is one of our key economic sectors, worth £4.2billion to the Welsh economy each year and visitor attractions are an important component of the industry.
"We have a rich and diverse range of attractions in Wales many of which reflect our unique culture, history, heritage and natural environment which are enjoyed by millions of people each year while also providing an important educational resource."
Museums and art galleries were the most visited attractions (5.3m visitors) followed by country parks, gardens and other natural attractions (4.9million visitors) and historic properties (2.9million visitors).
Amongst attractions providing a breakdown of visitor origins, just under half (48%) of the visitors were local people, with 44% from the rest of the UK and 8% from overseas. Overseas visitors are particularly important for historic properties accounting for nearly 20% of visitors , followed by industrial and craft attractions with around 14% of international visitors.
