En uno de sus valles recorrido por el río Iregua, está el Camero Nuevo, tierra de bosques, pastizales, cumbres y pequeños valles, donde se sitúan 13 pueblos con historia, tradiciones y leyendas, que siglos atrás se agruparon bajo la denominación de Hermandad de las 13 Villas.
In the past, Torrecilla was Head of the Judicial District, which included the both Cameros, the Old and the New. This judicial division existed until 1988 and, as a result, Torrecilla had a Court and a Notary, in addition to the head of the religious Archipriesthood and a prestigious weekly market.
It is currently the head of the Cameros County and offers multiple services, along with a rich cuisine and cultural activities such as the Solidarity Festival.
