In this photo, we see the remnants left over from visitors to the Tat Luang in Vientiane where visitors have placed incense and candles.
The stair railing at the entrance has the ນາກ nak (aka naga in English) which in Buddhist/Hindu mythology was a snake or serpent. Although, in reality these days, it looks more dragon-like.
In Buddhist scriptures, it was the nak that shielded the Buddha from the weather as he sat in meditation. Today, nak is symbolically a protector of the temple.
