Some of the West Midlands' most diverse architecture, history and culture will be available to the public free of charge later this month.
Launched yesterday at Wolverhampton Central Mosque by the Civic Trust and English Heritage, Heritage Open Days will give people the chance to visit all kinds of properties, including religious buildings, between September 8 and 11.
The tour will see 265 buildings in the Midlands open their doors to the public free of charge, some for the first time, and will provide tours, activities, and events for visitors of all ages.
Of the properties, ten are in Herefordshire, 44 from Shropshire, 12 in Staffordshire, 54 in Warwickshire, 104 in the West Midlands and 41 in Worcestershire.
One regional highlight will be the Wolverhampton Faith Buildings Trail, featuring the city's six main faiths - Christianity, Hinduism, Buddhism, Judaism, Sikhism and Islam.
The trail includes guided tours of religious buildings including the Darlington Street Methodist Church, the Shree Krishnan Mandir, Dr Ambedkar Buddhist Centre, the Ukrainian Catholic Church St Volodymyr and Olha, the Former Synagogue and the Guru Nanak Gurdwara.
English Heritage's West Midlands outreach officer Suzanne Carter said the event would encourage people to have a look around buildings which reflect the region's many religions, while learning about local history.
"Heritage Open Days celebrate England's diverse culture and heritage. Buildings of every age, style and function throw open their doors and take part, from Buddhist temples to parish churches, castles to factories, town halls to tithe barns," she said.
"This is a fantastic opportunity for everyone in the West Midlands to become involved and learn more about their local history."
English Heritage chief executive Dr Simon Thurley said: "Heritage Open Days is Britain's biggest celebration of history and culture.
"Hundreds of thousands of people take part across the country, reflecting the huge enthusiasm we have for our heritage.
"Each year a new range of properties and communities become involved so even if you are a veteran of Heritage Open Days there is something new to see and do.
"Who hasn't wandered past buildings in their street and wondered what lies behind those doors? Now is your chance to find out. We're inviting everyone to come along and join in."
Civic Trust spokeswoman Alexandra Rook said: " Heritage Open Days is for everyone. Organised locally by thousands of people who care about their environment and want to share their enthusiasm and knowledge with their visitors, it is a sign of a growing civic spirit.
"Each year more and more individuals and groups get involved, show off their place and engage with their local communities."
Additional events in Birmingham and the Black Country include a traditional Indian Rangoli art demonstration and workshop at Birmingham Museum and Art Gallery, in partnership with Arts Fest and a trail through Birmingham's medieval centre.
