VENUE PROPOSAL: When Donald Trump wanted to hold Miss Universe pageant at Masada. US president reportedly believed that having a beauty contest at palace built by Judean king Herod would be a good PR opportunity (Ben Sales, JTA via Times of Israel). For whom the PR would have been good was not specified. The 2011 pageant was held in São Paulo, Brazil, instead.
Background here. There have been operas at Masada but, as far as I know, no beauty contests.
