The mysterious Dolmen of Sintra... 🧭/ El Dolmen misterioso de Sintra...🚩 (En-Es)

Today I bring you a unique adventure for my travel blog and channel! Exclusively for Hive, we're going to hike the "PR10 STR" trail, one of the lesser-known trails in the Sintra area, and one that holds a mystery. We'll be explorers trying to unravel the mystery of the "Anta." Is it a 5,000-year-old human construction? Or is it a whim of nature? You can draw your own conclusions... Meanwhile, I'll show you the way...🏔️🌏

In this picture we can see a comparison between a traditional Dolmen and the Anta Adrenunes, both have very different characteristics in origin and symmetries, but what caught my attention is that it is thought that it was used for ritual purposes, even though they did not bury a person, and that certainly warrants investigation.🙇🏻‍♀️🧭

En este cuadro podemos ver una comparacion entre un Dolmen tradicional y el Anta Adrenunes, ambos tienen caracteristicas muy diferente tanto en origen, como en simetrias pero capto mi atencion que se piensa que si fue usado como fines de rituales, mismo que no enterraran a una persona y eso amerita claro investigar.📍👨🏻‍🏫

Where to go?📍🌏 / Hacia donde ir?🚩📸

Coordinates: 38° 46' 40" N / 9° 27' 51" W🌏🧭 / Coordenadas: 38° 46' 40" N / 9° 27' 51" W📍🌏

The dolmen is located behind the mountain where the Santuario da Peninha is situated. You can actually take the same route and visit both sites, but be prepared physically and mentally. It's a brutal trail with more than 6 hours of hiking, and you'll have to climb over 500 meters and then descend to reach the dolmen. If you're up for it, you should leave very early, between 5 and 6:00 am.🏞️🏕️

El dolmen queda atras de la montana donde se ubica el Santuario da Peninha, en realidad puedes hacer la misma ruta y conocer los dos locales, pero preparate fisica y mentalmente es un sendero brutal con mas de 6h de caminata y tendras que subir mas de 500m y luego bajarlos para llegar al Dolmen, si te animas debes salir bien temprano 5-6:00am🚙🧭

A trail for experienced hikers📍🌏 / Un sendero para experimentados🚩📸

I'd like to tell you it's a trail for the whole family, but no! If you start from where I began: "Alcabideche," it's an extremely difficult route, and of course, it's not suitable for children. What you could do is drive your vehicle to within 1 km of the Dolmen and then walk to the tourist site, but you'd take away all the excitement.📍📸

Me gustaria decirte que es un sendero para toda la familia pero no! si partes desde donde comence yo: "Alcabideche" es una ruta extremadamente durisima, y claro que no es apta para ninos, lo que podrias es llegar con tu vehiculo hasta 1km cerca del Dolmen y ahi si caminar hasta el sitio turistico, pero le quitarias toda la emocion.🏔️🌏

Janes Village📍🌏 / Aldea de Janes🚩📸

Trails🚩

Janes is one of those isolated villages in Sintra, located 20 minutes by car from the town center or historic district. I always suggest that when hiking in Sintra, you should come well-prepared because it's very rare to find a place to buy food or drinks! Personally, I love places without tourists, where I can be alone walking in nature. If you share this preference, then this trail is perfect for you.🌍📍

Janes es una de esas aldeas que esta aislada en Sintra y que se localiza a 20min en vehiculo del Centro o casco historico, siempre sugiero que hacer senderismo en SINTRA es venir bien preparado porque es demasiado raro localizar un sitio donde comprar alguna bebida o comida! en lo personal me encantan los lugares sin turistas y que solo este yo caminando en la naturaleza, si tienes los mismos gustos entonces el sendero se adecua a tu exigencia.🗺️🚩

If the weather conditions are ideal, believe me, you'll find one of the best viewpoints in Portugal here, and I'm not exaggerating! Unfortunately for me, it was cloudy and windy, and it even rained a little at one point, so I wasn't very lucky, but I'm sure you'll love the view.🚩📍

Si las condiciones climaticas son las ideales creeme que tendras aqui uno de los mejores miradores de Portugal, y no exagero! para mi suerte estaba nublado, viento, en un momento llovio un poco asi que no corri con suerte, pero seguro te gustara el paisaje🌻🌺

Some tips for the route📍🌏 / Algunos consejos para la ruta🚩📸

✅ Since it's a long route, prepare with comfortable clothing, long pants, a hat, and walking sticks.
✅ The trail is not circular; you will have to return to the starting point. You might want to use Google Maps if you are unfamiliar with the area to avoid getting lost.
✅ Do not interact with nature by disturbing, breaking, or bothering animals; stay on the paths
✅ Do not touch the fauna and flora, do not leave litter, do not destroy the ecosystem, stay on the path
✅If you are with other elderly people or children, use a vehicle to get closer to the dolmen.

Wild Nature📍🌏 / Naturaleza Salvaje🚩📸

The landscapes are amazing, aren't they? You won't find anything like Sintra anywhere else in Portugal. The closest thing is Arrábida, but it doesn't have the same atmosphere and scenery, plus there aren't such tall pine trees and rocks like these.📸🏞️

Asombroso los paisajes no? como Sintra no vas a conseguir en ninguna otra parte de Portugal, lo mas parecido es a la Arrabida y no tienes la misma atmosfera y paisaje, ademas que no hay pinos tan altos y estas piedras.🚙🧭

a little piece of travel!🌏🧭 / un pedacito de viaje!📍🌏

What is the geology of the area like?🌏🧭 / Como es la geologia de la zona📍🌏

I don't remember if I ever mentioned it on my blog, but Sintra is the result of a volcanic explosion millions of years ago, so it's common to see rocks like granite and syenite. This means you see rocks in places where it seems impossible they could have fallen.🏕️🌋

No recuerdo si en alguna vez lo mencione en mi blog pero Sintra es el resultado de una explocion volcanica hace millones de anos, por tanto es comun ver rocas de tipo: Granitos, Sienitos, todo esto hace que se vean rocas en sitios donde parece que no hay forma que cayeran aqui📸🌏

I could say I have some experience with dolmens; it's not my field of research, but I've visited and researched many, so I have some technical knowledge about this prehistoric engineering work. If you want to learn more, just look for this post:📍📸

Podria decirse que tengo un poco de experiencia sobre el tema de los Dolmenes, no es mi campo de investigacion pero ya visite muchisimos e investigue muchos tambien, asi que tengo un conocimiento tecnico sobre esta obra de ingenieria prehistorica, en realidad si quieres aprender mas basta con buscar este post:👨🏻‍🏫🙇🏻‍♀️

The dolmen was investigated in the late 19th and early 20th centuries. One of the key characteristics for determining whether a megalithic complex corresponds to a dolmen is the presence of buried bones or fragments of objects, all dating from the fifth to the third century BC. Although Adrenunes resembles a dolmen, no bones were ever discovered.📸🧭

El dolmen fue investigado en finales del siglo XIX y tambien principios del XX, una de las caracteristicas primordiales para descartar si un conjunto megalitico corresponde a un Dolmen es por que hay huesos enterrados o fragmentos de objetos, y todos datan de el quinto al tercer siglo antes de Cristo, apesar que Adrenunes tiene la similitud de un Dolmen nunca se descubrieron huesos.📍🚙

alt

The Dolmen has many interesting features that suggest it was used in prehistoric times and that people were buried there. However, I believe the most valid theory is that it was a structure built by people, not for burials, but for worshipping gods, since the setting sun illuminates the entrance, as if it had been intentionally placed that way.🏕️🌏🌋

El Dolmen reune muchas cosas interesantes como para pensar que si fue usado en la era prehistorica y que se enterraban personas, sin embargo yo creo que la teoria con mayor validez es que fue un local construido por personas pero no para enterrar, si no para hacer culto a dioses, ya que el sol en la puesta ilumina la entrada, como si hubiese sido colocado asi de forma intencional🌻🌺📍

My final opinion🌏🧭 / Mi opinion final📍🌏

alt

=================================================================================

En:

Personally, as a scientist, I need more evidence to prove that this is a dolmen; we cannot base our conclusion solely on its shape.📍
It wasn't a coincidence of nature; many pieces of evidence show that there was human intervention here.📍
A unique experience for adventurers and budget tourists📍
A trail with a 4/5 star rating in my opinion📍

=================================================================================

Es:

En lo personal como cientifico necesito mas evidencias que demuestren que esto es un Dolmen no podemos basarnos solo en la forma📍
No fue una casualidad de la naturaleza, muchas pruebas demuestran que hay mano humana aqui📍
Una experiencia unica para aventureros y hacer turismo economico📍
Un sendero con una evaluacion de 4/5 estrellas para mi gusto📍
