The Kingsbury hotel is a massive unmistakable building if you're driving by Galle Face - it's one of the grander ones in the city, with an old Victorian theme (at least with the interior). The views from the hotel, especially from the rooftop bar, are pretty cool. And we thought the hotel deserved points for aesthetics, if the general vibe of extravagance doesn't put you off.
St. Mary's Church is a beautiful place to visit if you're in Negombo. The stained glass and the paintings spanning the church's entire ceiling are awesome to witness, especially considering that the church goes back almost a century and a half.
