Harry Potter and Porto’s Hidden House
One of the delights of Porto’s architecture is the Hidden House between two churches. There is some claim that it inspired J K Rowling and her Harry Potter series. Is this connection true, or is the city trying to cash in on its celebrity connection?
History
There are two churches in Porto’s centre which are (almost) next to one another. These are the Church of Carmel and the Church of the Carmelites. (Igreja do Carmo and Igreja dos Carmelitas, in Portuguese.) It’s unusual to have two places of worship so close to each other, and more unusual to have them side-by-side.
Religious laws at the time forbade churches to be built next to one another, but this may be a legend rather than a hard and fast rule1. The architects got around this “rule” by inserting a tiny house – 1 metre (3 feet) wide! – between the two churches2. Locals soon started calling this Casa Escondida (The Hidden House)3.

The three-storey house is open for visitors now but people lived in it as recently as the 1980s4. Chaplains lived there, as did artists and tradesmen who worked on the churches5 6. It was also used for secret meetings between Napoleon’s invading forces and the Portuguese resistance during the Siege of Porto7.
These churches were sanctuaries, unlike the ones in Malta.
Nowadays, it sports a Spartan interior, showing how people lived there.

Igreja do Carmo
Built between 1756 and 17688, this is the more recent of the two9 10,

Igreja dos Carmelitas
Built between 161611 and 162812 13, this started off being part of a convent for the Carmelite order14 15 of nuns16. This is one of the oldest buildings in the historical part of the city17.
Architecture and art
Looking at the two buildings it’s easy to tell they’re two separate ones rather than one single place. It’s not so obvious to see where the Hidden House is.
The Igreja do Carmo
The church and has a neo-classical facade sporting the figure of Saint Anne18. The layout is the work of architect José de Figueiredo Seixas. Seixas was a disciple of Niccolo Nasoni19 who designed and built most of Porto20.
The church decorated the eastern wall with traditional local-made Portuguese tiles. If you approach the buildings from this side, it captures the eye and it’s hard to notice anything else. They added this in 1912 and the image depicts the founding of the order21.

The interior of the church is a marvel of rococo and baroque, rich in decoration and wood carving22 23 24.
Igreja dos Carmelitas
The church has a classical granite25 facade and a single bell tower, which its neighbour doesn’t have26 27.

The interior of the church is a marvel of rococo and baroque style, rich in decoration and golden28 wood carving29. It took them till 1650 to finish the interior, long after they consecrated the church30.
Popular culture
Best-selling author J K Rowling used to live in Porto in the early nineties. She has confirmed drawing inspiration for her Potter series from Porto. Local guidebooks are full of proud connections to the Harry Potter universe.
Visitors inundate the Lello bookstore, for example. Here they see the inspiration behind the Flourish and Bolts’ bookshop where Potter and his friends buy their magic books31. When I visited, the queue to enter was more than 10 deep, despite the scorching temperatures.

There are many connections between a hidden house and Rowling’s stories. The first place I thought of was the Order of the Phoenix, at 12 Grimmauld Place (also a hidden building). It’s worth noting Rowling never acknowledged such a connection. The information panels in the house hint at this, without mentioning her by name.
Whether there is a Potter connection or not, it is a beautiful part of old Porto and well worth a visit.
