Tiedra is a small hilltop town in the region of Tierra de Campos. It has traditional vernacular architecture, with stone and adobe houses, red clay roof tiles, and narrow streets typical of rural Castile. Significant buildings include the thirteenth century Castle of Tiedra, the Church of El Salvador, and the nearby Tiedra Astronomical Centre. The Ermita de Nuestra Señora de Tiedra Vieja is a historic chapel on the outskirts of Tiedra.It is especially notable because it stands on the hill where the original settlement of Tiedra once existed, combining Baroque religious architecture with an important archaeological site that preserves evidence of much earlier Vaccean and Roman occupation. Agriculture is centred on cereal crops such as wheat and barley, together with vineyards and lavender cultivation. Tiedra stands out from similar medieval towns because it combines its historic heritage with astrotourism and lavender production, attracting visitors interested in both astronomy and rural landscapes.
