In the 20th century, it was classified as a National Monument.
It's nice to discover history through this beautiful and simple castle.
Nice Castle in the middle of town. Easy parking and great views. Elevator was broken which would have easily let my mother up onto the rampart.
Entered very quickly, was near closing time but the staff let me have a quick peak. Good to know I've to go back
Fantastic little rustic village, where life slows down to a crawl, local market looked amazing ( closed on mondays ) fantastic 13th century castle also closed on monday, but thats ok on the flip side we picked up a 10 year bottle of local red wine for under 5€,
Beautiful pearl of Alentejo! Worth visiting while being around.
It was great to go back in time love history
Great renovation on this monument. Great views. It would be fun to have some animation on it during some days of the year.

It's amazing how a 2000 year bridge is still standing. Impressive engineering skills.

Amazing place to visit, especially after the renovations. Yet another example of the diversity of cultural offers in Alter. Pay attention for because there are different working hours in summer and winter.
Beautifully well kept gardens
(Translated by Google) This is a cultural space/museum, as well as a tourist office. It provides a little more information about the large agricultural houses of Alto Alentejo. The residential building is of Baroque architecture. It is a two-storey urban manor house. There are several spaces with clearly identifiable functions. The ceilings of the main floor are decorated in the 18th century (painting and plasterwork). Its gardens are worth a leisurely visit. It is a Portuguese garden, attached to the house, with several interesting elements: houses for agricultural use, a water wheel, tanks and irrigation systems, lakes, leisure areas, living materials with interesting species. (Original) Aqui funciona um espaço cultural/ museu, bem como o Posto de Turismo. Dá-nos a conhecer um pouco mais sobre as grandes Casas Agrícolas do Alto Alentejo. O edifício residencial, é de arquitectura barroca. É um solar urbano de 2 pisos. Múltiplos espaços com funções claramente identificáveis. Decoração setecentista dos tectos do andar nobre (pintura e trabalhos em massa). Os seus espaços ajardinados merecem uma visita descontraída. É um jardim à portuguesa, adossado à casa, com vários elementos de interesse: casas de utilização agrícola, nora, tanques e sistemas de rega, lagos, espaços de lazer, materiais vivos com espécies interessantes.
(Translated by Google) A very well-kept and beautiful manor house. The entrance fee for adults is €2, but it is possible to buy a single ticket that includes the castle and Roman ruins. I really liked the house. However, on the day I visited I did not have the opportunity to take a guided tour. (Original) Casa senhorial muito bem cuidada e muito bonita. O preço de entrada para adulto é de 2€ mas é possível a compra de bilhete unico que inclui castelo e ruinas romanas. Gostei muito da casa. Contudo, no dia que visitei não tive oportunidade de visita guiada.
(Translated by Google) The Casa do Álamo is not only a museum but also houses the Tourist Office. A place to learn a little more about the great agricultural houses of Alto Alentejo. (Original) A Casa do Álamo além de núcleo museológico alberga o Posto de Turismo. Local para conhecer um pouco mais sobre as grandes Casas Agrícolas do Alto Alentejo.
(Translated by Google) I don't have much to say about the palace itself, but the gardens, which are completely abandoned, are a shame for anyone who knew them 30 years ago to see how abandoned everything is now. (Original) Do palácio em si não tenho grandes comentários a fazer mas dos jardins, completamente abandonados faz pena a quem tenha conhecido os mesmos há 30 Anos e ver como tudo está agora ao abandono.
(Translated by Google) Beautiful to visit and get to know. (Original) Bonito de se visitar e conhecer.
