About Ex-Voto( Wikipedia):

An ex-voto is a votive offering to a saint or divinity. It is given in fulfillment of a vow (hence the Latin term, short for ex voto suscepto, "from the vow made") or in gratitude or devotion. Ex-votos are placed in a church or chapelwhere the worshipper seeks grace or wishes to give thanks. The destinations of pilgrimages often include shrines decorated with ex-votos.
