The reasons behind this curious curtain placement are still being explored. Some speculate that it might be a traditional architectural feature passed down through generations. It could potentially serve a practical purpose, such as providing better protection from the sun's rays or enhancing privacy in a different way compared to the typical inside - drawn curtains. Others believe it might be a local innovation to adapt to the specific climate or cultural preferences in Portugal.
As word spreads about this odd curtain arrangement, more people are taking notice. Whether it will remain a local quirk or inspire similar installations in other parts of the world remains to be seen. This simple yet distinct aspect of Portuguese life has certainly added a touch of intrigue to the country's cultural and architectural landscape.
