Served as the presidential palace between 1919 and 1940, this building is one of the most important locations of Lithuanian history. Once the home of presidents like A. Smetona, K. Grinius and A. Stulginskis, today it hosts various cultural events, as well as permanent and temporary exhibitions.

St Peter & Paul's is the largest Gothic structure in Lithuania, and the country’s only Gothic church with a basilica floor-plan as opposed to the usual cross-shaped design. Its one-of-a-kind interior, with its nine altars, is also breathtaking. During its history, it was rebuilt several times, which has given the building an eclectic look, with some Renaissance features included.

Built on the land occupied earlier by the Corpus Christi hospital, one of the city's medieval hospitals. In 1558 the city exchanged plots with Archishop Esteban Almeyda and the hospital was relocated to the Parish of Santiago. The building may have started in the 16th Century, soon after the establishment of the Orihuela Bishopric. It underwent profound changes in the 18th Century under the reigns of Bishops José Flores Ososrio and Pedro Albornoa Tapia. In the mid-20th century, it lost its original functions, was restored at the beginning of the 21st Century and is currently home to the Diocese Museum of Sacred Art. At the back, facing the river, there is a gallery with semi-circular arches. Inside, another striking feature is the cloister with heraldic decoration, the main staircase of Alicante marble and the dome built on an octagonal base, with exterior cobalt blue glazed tiles.

Further inland, in the southern part of the island, lie the so-called masticochoria (mastic villages). These well-preserved, fortified villages date from the 14th-16th centuries and were centres for the cultivation of mastic. Mastic is the sweet-tasting gum of the lentisk bush, which was exported all over the Mediterranean – and the area still produces around 300 tonnes of mastic every year. The most picturesque villages are Pyrgi, with its houses decorated in black and white geometric patterns called xysta Mesta, where towers and walls surround a baffling labyrinth of village streets as well as Olympoi and Vessa are all a worth a visit.
