The Markwarth Collection or "Solomon Islands War Museum (SIWM)" or "Renadi World War II Museum" is the Markwarth brothers private collection of World War II artifacts and relics they have collected since their youths primarily from Guadalcanal. Visits are by appointment only. Founded by brothers Kurt Markwarth and Anders (Jurgen) Markwarth who grew up in Honiara and are the sons of Mr. Markwarth the founder of Markwarth Oil Ltd.
The Markwarth Collection is stored at three locations around Honiara: a storage area and former oil drum factory at Renadi, Lela Beach Resort and a storage yard on Point Cruz near Markwarth Oil. The collection is built around substantial small arms, ordnance, artillery and other relics collected since their childhood. During the late 2000s to the present day, the brothers collected wartime scrap and salvaged aircraft crash sites from Guadalcanal including both Japanese and Allied aircraft. During 2009–2016, the Markwarth brothers salvaged wartime wrecks including M3 Stuart Tank T20 (2009) and P-38J Lightning 43-28570 (2013) and A6M2 Zero 2666 (2017).

Renadi Collection Oil Drum Plant
Other relics are stored at another Markwarth property their former oil drum manufacturing plant and industrial storage area also at Renadi. Displayed outdoors is an LVT Amtrac that Kurt Markwarth claims is under restoration to running condition and a Japanese steam roller that they also might plan to restore.
Lela Beach Resort Collection
Kurt Markwarth's Lela Resort collection is located in the former Lela Beach Resort Hotel. The former restaurant is a indoor air conditioned display area with lighting and security cameras for small arms and relics collected from Guadalcanal. Outdoors are several Japanese field guns and artillery pieces and some aircraft wreckage.
Point Cruz Yard
Anders Markwarth's yard at Point Cruz is a fenced area adjacent to the road near the port area near Markwarth Oil. This yard has shipping containers and aircraft wreckage. The proximity to the port area has allowed containers of wartime material to be exported overseas, reportedly for restoration and to be returned. During the middle of July 2017, P-38J Lightning 43-28570 and A6M2 Zero 2666 were exported from this Point Cruz and shipped to Australia.
