The Basque Country is a cross-border cultural region that has a distinctive culture including its own language, customs, festivals, and music. The Basques living in the territory are primarily represented by the symbol of the flag Ikurriña, as well as the Lauburu cross and the Zazpiak Bat coat of arms. The Gernikako Arbola and the Agur Jaunak are its most recognizable anthems in music, and the oak its most revered tree (cf. the aforementioned Tree of Gernika).
