Further west of the Towers of Yemliko (a group of towers constructed as multistorey burial chambers), deeper into the hills, are plenty more funerary towers, some totally dilapidated, others relatively complete. By far the best preserved is the Tower of Elahbel, which is situated about 500m west of the Yemliko group. Built in AD 103, it has four storeys and could purportedly accommodate up to 300 sarcophagi. It's possible to ascend an internal staircase to visit the upper storey tomb chambers and to get out onto the roof.
Also here is the chamber that formerly housed the Hypogeum of Yarhai, dismantled and reconstructed in the National Museum.To visit Elahbel it's necessary to buy a ticket at the Palmyra Museum and join an organised foray led by a caretaker; these depart at 08:30, 10:00, 11:30 and 16:00 Wednesday to Monday and 09:00 and 11:00 Tuesday. From October to March the last visit is 14:30. At all other times the tomb is locked. The visit also includes the Hypogeum of the Three Brothers, which makes it worthwhile.
